Previews of our wireless industry thematic research:

wireless industry thematic researchRF Semiconductors: Mislabeling parts doesn’t help Huawei’s predicament. (August 14, 2019)
Excerpt: A recent teardown of Huawei's Mate 20 X 5G phone by Tech Insights misidentifies several RF components, confusing small, inexpensive parts for large, high-ASP modules. These errors were amplified Monday by a competitor's note citing Tech Insights’ analysis as proof that Chinese component manufacturers, more specifically HiSilicon, are replacing U.S. RF modules with internally sourced devices. This is not correct.

wireless industry thematic researchRF Semiconductors: Why Huawei needs U.S. components to build flagship smartphones. (August 9, 2019)
Excerpt: The U.S. government’s ban on most exports to Huawei has stoked speculation the Chinese OEM can replace U.S. RF components with Japanese, Taiwanese and Chinese suppliers. This is highly unlikely. The size and performance requirements for a competitive LTE Advanced, LTE Pro or 5G phone require OEMs to employ complex, high-density RF modules that are only available from Broadcom, Qorvo and Skyworks; there are no other alternatives.

wireless industry thematic researchRF Semiconductors: You can’t build a flagship smartphone without U.S. RF semiconductors. (July 27, 2019)
Excerpt: The Huawei kerfuffle had investors questioning the possibility of the Chinese OEMs replacing U.S.-sourced semiconductors in the RF front-end (RFFE) and carrying on as normal. Huawei has made claims to that effect.

wireless industry thematic researchWelcome to the 5G logo wars. (June 27, 2019)
Excerpt: We've been told by several folks deep across wide swathes of the wireless food chain, the killer application for 5G is the logo on the box that says "5G". It certainly seems to be playing out that way. T-Mobile has built out a 4G network on its new 600MHz band (Band 71) onto which it will dabble the smallest spec of 5G - higher density modulation on a paltry 10MHz of the 35MHz band and then crown the entire service "5G".

wireless industry thematic researchOver-charging for 5G modems has consequences. (June 20, 2019)
Excerpt: Even before the FTC ruling, Qualcomm’s grip on the cellular baseband market was slipping. Intel emerged as a suitable replacement at Apple (at least for 4G), Huawei sourced nearly all its needs from HiSilicon, and Samsung was using its own LSI modem in everything from the Galaxy and Note to mid-tier models. Oppo and Vivo ebbed and flowed with MediaTek while Xiaomi was heavily committed to Qualcomm.

wireless industry thematic researchThou shalt not pass. (June 18, 2019)
Excerpt: RFFE modules will grow in size and complexity, but they won't combine low with mid-high bands. Having tracked the evolution of RF front-ends from before Triquint introduced the PAD in 2005, we've witnessed the growth in RF modules from single band to 12 bands in the 2018 modules. The relentless increase in size and content has investors wondering when they will see one module to rule them all; a single placement device combining low, mid and high bands.

wireless industry thematic researchMassive MiMo is French for WiFi. (June 13, 2019)
Excerpt: Any conversation about 5G in cell phones inevitably involves discussion of massive MiMo (beam steering antenna arrays) because there's no practical way to establish a radio link to a mobile phone over 5G frequencies (Sub-6 or mmWAVE) without them. This makes "5G" and "massive MiMo" synonyms at least as far as connections to cell phones are concerned. The problem for carriers is that "massive MiMo" and "Mobility" are antonyms.

wireless industry thematic researchImpact of Huawei ban on phones, base stations and semiconductors. (May 22, 2019)
Excerpt: On Wednesday, May 15, the U.S. government banned U.S. firms from shipping products to Huawei, causing an extended sell-off in semiconductor and equipment stocks. Heavily reliant upon American technology, Huawei finds itself in a similar position as ZTE when it was blacklisted in April of last year. That ban nearly drove the company out of business and even after it was lifted in July, the damage persisted as many customers shifted to other suppliers that didn’t face the possibility of future disruptions.

wireless industry thematic researchGaN is good, but not for handsets. (May 16, 2019)
Excerpt: After a decade of gestation, GaN is finally coming into its own. The advantages over silicon and GaAs in power output and efficiency are substantial enough to get the notoriously parsimonious wireless network OEMs to pay up for GaN in 5G base station power amplifiers. The defense industry has been using it for years and every new hypersonic, stealth and ballistic missile threat increases the depth and breadth of its reach in land, sea and airborne radar.

wireless industry thematic researchThe ripple effect of the Apple-Qualcomm settlement. (April 30, 2019)
Excerpt: The litigation settlement between Apple and Qualcomm will ripple through the food chain, altering content expectations for the various component suppliers. The biggest beneficiary is obviously QCOM which experienced its largest single-day stock price increase in nearly 20 years; a testament of how much more important a settlement was to Qualcomm than to Apple, which was up only 1%.

wireless industry thematic research5G and the fallacy of faster duty cycle. (April 22, 2019)
Excerpt: 5G: If you're deep in the mobile cellular world and given to technical discussions sooner or later, you’ll probably find yourself in threadbare debates with 5G evangelists over use cases. The starting point is usually how the lack of spectrum in the legacy cell bands pushed 5G to higher-frequencies. High-frequencies don't propagate well so getting enough signal to the phone requires “massive MiMo”.

wireless industry thematic researchEuphoria over Apple settlement may be short lived but it’s not good news for Qorvo. (April 17, 2019)
Excerpt: 5G: Intel thought it could, but Apple didn’t share that confidence. As recently as last week, our checks deep in the baseband supply chain showed a high degree of confidence that Intel would deliver its 5G modem to Apple on time. It also revealed Apple didn’t share this opinion and in fact, had little confidence in Intel’s ability to meet its schedule.

wireless industry thematic researchThe 5G Fairy Tale. (March 27, 2019)
Excerpt: 5G is turning into a pretty nice little bubble, especially for Qualcomm. The sell-side is teeming with reports of Qualcomm’s success in landing modem and RF content in most 2nd and 3rd tier 5G phones slated for release this year.

wireless industry thematic research4G Pro is the new 5G. (March 6, 2019)
Excerpt: Of the three band groups that will light up the 5G icon on phones this year (low (B71), mid (B48), high (mmWAVE)) all will be “anchored” by a 4G link. Anchoring in this context means “made usable” because none of these 5G bands can stand on their own and most won’t exist for most users in most areas.

wireless industry thematic researchThe cost of testing 5G phones could kill them at birth. (February 4, 2019)
Excerpt: Unlike in LTE, 5G requires MiMo, which broadcasts multiple signals on multiple antennas, every one of which must be tested across all bands, modes and use cases. With so many more combinations to deal with, test equipment for 5G is extremely complex, much more so than for 4G.

wireless industry thematic researchApple's future in phones. (January 12, 2019)
Excerpt: Apple’s problems don’t have to lead to failure, but in the long run they probably will. The path it will doubtlessly follow was forged by Ericsson in 2001 and retraced by every major handset OEM failure since . Product problems at each of those companies undercut unit sales, ate into margins and put them further behind their competitors.

wireless industry thematic researchWhat to expect for Apple & the RF semi suppliers. (January 3, 2019)
Excerpt: Apple’s problems are nothing new and likely to become more acute. Having covered the handset industry since 1997, we had a front row seat to a long procession of failures in phones starting with Ericsson in 2001 followed by Siemens (’05), Motorola (’07), Sony-Ericsson (’08), Nokia (’09) and finally Blackberry (’12).

wireless industry thematic researchTrade wars, embargoes, hurricanes - RF content is still going up. (October 23, 2018)
Excerpt: Building a 4G phone without U.S. components is like trying to launch satellites without rockets. A recent note out of a competitor calls for zero content growth at U.S. RF semiconductor manufacturers on the belief that Chinese OEMs are shifting to Japanese suppliers to ameliorate the impact of trade war restrictions.

wireless industry thematic researchWill the U.S./China trade war impact iPhone sales? (October 16, 2018)
Excerpt: The trade war could affect iPhone sales, but we believe there are other more important factors impacting unit sales which have nothing to do with China. Saturation in high-end demand. High-end smart phone unit sales have been stagnant for several years now, a trend evident in both Apple and Samsung’s results.

wireless industry thematic researchQualcomm's campaign to put a man on Mars. (October 12, 2018)
Excerpt: We’ve received a plethora of requests to handicap Qualcomm’s prospects in 5G, particularly in mmWAVE. These are largely the result of the marketing campaign Qualcomm pursued in January to fight off Broadcom, which was amplified more recently by a sell-side competitor’s breathless regurgitation of the company’s marketing flyers as research.

wireless industry thematic researchWhat's ailing Wireless? (September 19, 2018)
Excerpt: Over the last several weeks we have fielded a large number of investor calls on the weakness in the RF semiconductor stocks, especially SWKS and QRVO. Most questions focus on three primary concerns but a poll of large holders and the companies themselves suggest there are four concerns pressuring the stocks.

wireless industry thematic researchBull case on Qualcomm's 5G RF is far off the mark. (August 8, 2018)
Excerpt: Lowering price targets on the threat of losing 0.8% in revenue in two years seems nonsensical? A competitor’s note on Monday claiming Qualcomm’s gains in 5G RF are a blow to Skyworks and Qorvo is far off the mark in our opinion, stretching comments from a single “expert network” consultant to illogical conclusions not backed by events and trends on the ground.

wireless industry thematic researchThe Big Challenge for 5G (June 28, 2018)
Excerpt: It’s difficult to make a singular statement about 5G other than it’s the Tower of Babel for wireless standards; a technology looking for a market. Like the wireless broadband systems of the early milieu, 5G is just the latest version of the “If you build it, they will come” school of economics.

wireless industry thematic researchThoughts on GaN (June 19, 2018)
Excerpt: The International Microwave Symposium (IMS) was held in Philadelphia last week. It may sound like a conference on cooking, but it’s actually one of the preeminent gatherings of engineers and scientists in RF semiconductors.

wireless industry thematic researchQualcomm vs. Broadcom: Checkers or Chess? (February 13, 2018)
Excerpt: The International Microwave Symposium (IMS) was held in Philadelphia last week. It may sound like a conference on cooking, but it’s actually one of the preeminent gatherings of engineers and scientists in RF semiconductors.

wireless industry thematic researchPoints of interest on RF. (January 16, 2018)
Excerpt: The 5G filter story is being muddled.

wireless industry thematic researchLikely scenarios for Broadcom’s acquisition of Qualcomm. (November 5, 2017)
Excerpt: We don’t believe an acquisition of Qualcomm would herald a sea-change in Broadcom’s business model although it will upend the cellular modem industry.

wireless industry thematic researchWhat to expect on the quarter and in guidance for 4Q17. (October 26, 2017)
Excerpt: With so many moving parts in the mobile phone business and such large exposures to the big three OEMs (Apple, Samsung, Huawei), it’s often difficult to forecast hits and misses for Skyworks and Qorvo in individual quarters.

wireless industry thematic researchBig changes afoot in RF semiconductors. (September 15, 2017)
Excerpt: Carrier’s quest for the 1Gbps phone is proving a boon to RF semiconductors. We just completed a series of technical discussions with leading companies and engineers in semiconductors and handsets, and have concluded the quest for a 1Gbps phone will be a boon for the leading RF semiconductor companies.

wireless industry thematic researchiPhone 8: What to expect for new bands. (September 11, 2017)
Excerpt: We’ve been asked to comment on a recent note postulating on the possibility of various bands showing up in Apple’s new phone. Having tracked RF filter development for many years, we are familiar with the history, progress and likelihood of deployment of all the bands mentioned in the note.

wireless industry thematic researchRF Semiconductors – What to expect for the RF stocks with Apple’s upcoming phone release. (July 7, 2017)
Excerpt: We’ve fielded several questions about variations in RF content by SKU, with most investors expecting three new models in September: upgrades to iPhone 7 and iPhone 7S, and a new high-end flagship, iPhone 8. We expect RF content gains in all models.

wireless industry thematic researchRF Semiconductors – Trends for 2017. (January 18, 2017)
Excerpt: We are highly confident that content will increase in 2017 at all the major handset groups: Apple, Samsung, China Inc. (top 10 Chinese OEMs), and China white-box (MediaTek, QRD, Spreadtrum). The largest percentage increase will almost certainly be in China white-box phones where MediaTek is accelerating its move to PADs.

wireless industry thematic researchRF Semiconductors – Even if iPhone’s release schedule is stretched (unlikely) it will have no bearing on RF. (June 4, 2016)
Excerpt: How can Apple stretch its phone release schedule to three years when it doubled the models and halved its time-to-market for iPhone in 2016? A news report out of Asia suggests Apple will extend the revamp schedule for iPhone from two to three years because of slowing demand. While this is certainly possible, we don’t believe it’s likely…

wireless industry thematic research iPhone 6S: Teardown analysis. (September 25, 2015)
Excerpt: Total RF content up ~25% y/y for iPhone 6S. The teardown photos published last night confirm our forecast of a higher overall RF content from an increase in the number of LTE bands, a move to MIMO in the Wi-Fi section and larger, more complex diversity receive modules. The final word on how much all of this is worth will have to wait until the quarterly reports but discussions throughout 2015 suggest total additional spending will be in the $4.00 range, bringing iPhone 6S to about $24 in total RF content.

wireless industry thematic research RF Semiconductors - The Ten Most Common Fallacies about the RF TAM. (September 22, 2014)
Excerpt: #1: MMPAs- Multi band amplifiers will accelerate price erosion and destroy the market. The arrival of multi mode amplifiers (MMPA) in 2010 did drive down pricing, but only on a per-band basis, and then only in high-band count devices; they had no impact on ASPs for PAMs, PADs, FEMIDs or filters…

wireless industry thematic research iPhone 6 – A Detailed Teardown Analysis. (September 19, 2014)
Excerpt: Apple’s philosophy of minimum SKUs pushes total RF content up again. Contrary to what we thought two years ago, rather than segment its phones by region to reduce BOM costs, Apple has taken the opposite path, and decreased the number of RF SKUs to two with iPhone 6. This has increased the number of bands, as well as the complexity and cost per phone. Even if the unthinkable occurs and unit volumes are flat y/y, total dollars spent on RF by Apple will increase about 30% on higher content alone.

wireless industry thematic research RF Semiconductors – A thorough look into the RF Content of the iPhone 6. (August 11, 2014)
Excerpt: We believe that the iPhone 6 will have about $17 in RF content and that Avago will be the big winner. Our analysis suggests $16 - $18 in RF content for Apple’s new phone, lower than our previous forecast of $18 - $19, because we no longer expect envelope tracking (ET) to be used in the new phone due to the problems experienced with Qualcomm’s ET device (QFE11xx).

wireless industry thematic research A Field Guide to Filters (September 9, 2013)
Description: A meticulous 61-page primer explaining filter fundamentals (cost, insertion loss, temperature drift, distortion, and more), summarizing duplex filter products (front end modules, power amplifier duplexers, antenna filter modules), and comparing BAW vs SAW technologies.

wireless industry thematic research Understanding Disparities in the Food Chain’s Guidance for iPhone 5S. (July 27, 2013)
Excerpt: The stark differences in September 2013 period guidance between many of the vendors supplying parts to iPhone 5S has heightened concerns over share loss, slow demand and delays in the release of Apple’s next phone. Of particular concern is the huge difference between Triquint’s blow-out guidance and Qualcomm’s short-fall.

wireless industry thematic research RF TAM Analysis: A Detailed Look at Spending on RF Components for Mobile Devices (May 21, 2012)
Description: An in-depth 29-page report with detailed discussions of unit growth versus content compression, 2G to 3G conversion, High Density Amplifiers, and accelerating price erosion in commoditized devices.

wireless industry thematic research Estimates for phone demand in 2011 are too low. (December 13, 2010)
Excerpt: Phone growth could well exceed 20% y/y in 2011. Despite what appears to be a robust recovery in handsets, sell-in remains insufficient to satisfy the pent-up demand induced by three years of economic weakness. At 15%, the replacement rate for mobile phones hit a ten year low in 2009 after averaging 22% for the previous eight years.

wireless industry thematic research Android's opportunity to jump ahead of iTunes (July 8, 2010)
Excerpt: Next generation music platform is the major battle in the smartphone wars over the next 12 months. Last week's announcement that Google is activating 160K Android devices per day (a run rate that exceeds 14M per quarter), demonstrates Android’s ability to attract new users when combined with focused carrier marketing. Clearing that hurdle, the next test will be “stickiness”; the platform’s ability to retain users through several generations of replacements, as well as entice them to purchase secondary devices such as tablets and set top boxes.

wireless industry thematic research Zeitgeist: A cautionary look at the world’s appetite for handsets. (June 19, 2010)
Excerpt: The recession is in check, worldwide sales of handsets are up, demand for mobile semiconductors is booming and OEM inventory in the April reports remained below normal; everything seems to be going great so why are we so worried? Our growing apprehension stems from a slew of data points that individually may not mean much but in aggregate seem to spell trouble.

wireless industry thematic research Zeitgeist: Arguing RF Semiconductors. (May 2, 2010)
Excerpt: Nokia’s implosion last week stoked investor’s concern that the handset food chain is headed for leaner times, particularly the semiconductor manufacturers which posted record results even as Nokia’s margins reach record lows. The idea that component suppliers can’t do better than their customers is rooted in years of experience with the boom-bust cycles of the PC semiconductor industry. The rollercoaster of scarcity and surplus that drives that cycle is a direct consequence of Moore’s law and the inertia inherent in multi-billion dollar fabs.

wireless industry thematic research Zeitgeist: Drifting from Reality in Phones. (January 31, 2010)
Excerpt: We were asked to comment on an article from Thursday's Financial Times that endeavored to explain motives behind the big moves in mobile phone stocks over the last week. While well written, we found almost nothing in the article we could agree with but found it be an excellent summary of popular misconceptions about smartphones in general and Nokia/Motorola in particular. We present the article and our analysis below.

wireless industry thematic research Zeitgeist: Barbarians at the Gate (March 7, 2009)
Excerpt: My first introduction to the concept of handsets as commodities occurred in 1999 in a rapid fire debate with the head of a large technology fund who ran through the logic of why it was inevitable that handsets would follow the path of PCs and see margins plunge to low single digits. He had good reason for concern given that year saw Qualcomm-Sony, Philips and Lucent exit the business, Ericsson fall into losses and Motorola struggle to remain profitable after losing its lead to Nokia. Clearly mobile phones seemed to be following the curve of other consumer electronics where fat profits on early volumes disappear as manufacturing scale expanded and competition intensified.

wireless industry thematic research Zeitgeist: Dance partners are being chosen at the baseband ball. (February 14, 2009)
Excerpt: In the next several weeks, Freescale will announce the divestiture of its cellular business in what will be another major step in the ongoing consolidation of the baseband industry. The genesis of this divestiture goes back to Chicago 2000 when a small group of Motorola engineers began work on a credit card sized device that would become the RAZR. That phone’s success redefined the definition of style in handsets and set in motion events that would lead to the consolidation we are now witnessing.

wireless industry thematic research The Bigger Picture: The Whiplash Effect of Excess Inventory (January 31, 2009)
Excerpt: On October 12, 2008, we described a scenario in which a crescendo of bad news and preannouncements through the December period would culminate in a market bottom around February 1, 2009 (“Finding a Stable Bottom”). Our thesis has generally proven to be true even if the pace of events has been faster than we have anticipated.

wireless industry thematic research Deconstructing the Decline: Separating inventory burn from declining demand in 4Q08 reports. (January 20, 2009)
Excerpt: For the first time in history, the number of cell phones sold in the fourth quarter was lower than in the third period. Fourth quarter sales, which are typically up 20% sequentially, ended the year about 2% lower than in 3Q. Worse still was the timing. The freefall in late October hit manufacturers after the annual production ramp for the Christmas selling season had already begun, leading to bloated inventories even after production was cut-back in November.

wireless industry thematic research Finding a Stable Bottom. (October 12, 2008)
Excerpt: Now that the market has broken anchor from fundamentals and is in freefall, investors are wondering when we will see a stable bottom. Because failures in the financial sector and concerns about the economy are fueling the sell-off, it won’t be remedied by positive data points out of any of our companies in the short term. Indeed, the only thing that can stem the tide at this point is an end to the cascade of defaults and the collapse of confidence in the credit markets.

wireless industry thematic research Smartphone Wars: Google’s clone enters the fray. (September 27, 2008)
Excerpt: So begins the Android media juggernaut, Google’s formal entry into the Smartphone Wars, which have become the industry’s black hole consuming all media and emanating little reasoned critique. And while the Google faithful come off as deists compared to the Apple jihad, we believe expectations for the proliferation and impact of Android are optimistic. There are several major pitfalls that are routinely overlooked or discounted by new entrants in cell phones, especially those lacking experience in industrial grade communications systems and radio networks. That said, we believe the open architecture and flexibility of Google’s approach give it advantages that will help Android struggle through the rough road ahead.

wireless industry thematic research Google, Inc. – Special Report: Google enabled phone. Devil is in the details but potential exists for big gains. (November 5, 2007)
Excerpt: Marketing splash aside, it is too early to tell how the Google enabled phone will differentiate itself or how popular it will become. If Google concentrates on delivering seamless local based services (LBS), it could see dramatic gains. Location information is inherently valuable to mobile users, but is difficult to deliver seamlessly given the variety of technologies involved and the requirements for a visual interface.

wireless industry thematic research Multimedia Phones - Revisited: Review, Update and Outlook Since Our 2004 Report (October 6, 2006)
Excerpt: Two years ago we analyzed multimedia functions (pictures and music) in cell phones using their impact on handset mobility as a framework. We argued that pictures or music would be popular with subscribers only to the extent their utility in a mobile world outweighed their impact on the cost, size and power consumption of handsets. We concluded that imaging would not be popular with most subscribers because making handsets more appealing as cameras makes them less appealing as phones. Music, on the other hand, complements mobile phones because much of the utility of a standalone music player can be achieved with little impact to handsets, and music, like mobile voice service, can be used on the go.

wireless industry thematic research Multimedia Phones: A Quantitative Analysis of the Impact of Imaging and Music on Mobile Phones (September 10, 2004)
Excerpt: After years of anticipation, the age of multimedia cell phones seems finally upon us. Phones capable of more than just talk are populating the product lines of all major phone OEMs which now offer models that support data, music, imaging and video. Like PDA1 phones before them, multimedia handsets represent the state-of-the-art in radio and semiconductor engineering, boasting more performance and features than any other handheld device. But while technology has made such products possible, it has not always made them profitable.
