Qualcomm's RF360 design is changing the entire mobile RF industry revolutionarily. GaAs PA is facing a fierce attack from CMOS PA. Qualcomm's CMOS PA subverts the opinion that CMOS PA can only be used on low-end phones. Specifically for CMOS PA, Qualcomm designs QFE1100, which is a front-end module involved with envelope tracking technology. QFE1100 can help CMOS PA improve thermal efficiency, reduce heat by 30% and cut down power consumption by 20%.

ZTE’s flagship mobile phone Grand S II LTE uses Qualcomm’s CMOS PA -QFE2320 and QFE2340 for the first time. The combination of QFE2320 and QFE2340 can cover all major cellular modes, including LTE TDD / FDD, WCDMA / HSPA +, CDMA 1x, TD-SCDMA and GSM / EDGE, with the RF band of 700MHz to 2700MHz. Qualcomm has basically monopolized smartphone Modem or CPU markets, and may dominate the PA field. However, mobile phone vendors will still cooperate with GaAs PA suppliers in order to ensure their equal status.
Nevertheless, the focus of mobile RF industry has been shifting from PA to filter. In the 4G era, the most valuable part of mobile RF system is filter, especially BAW, rather than PA. The biggest difference between 4G and 3G lies in BAW which is an essential part for 4G. A regional LTE phone needs a BAW valued USD1.25, a SAW worth USD2.25 and a PA which only costs USD1.75. As for a global roaming LTE phone, a SAW tagged with USD3, a BAW with USD3.5 and a PA with USD2 are required.
The biggest event in the RF industry in 2014 must be RFMD’s takeover on Triquint. Triquint suffered consecutive losses in 2012-2013; in Q1 2014, its revenue...
