The market is bright for power amps in phones

LTE smartphones led to a bump in sales of RF power amplifiers in 2015 and the first half of 2016, according to Strategy Analytics ( Over the next five years, highly integrated multiband PA modules that include switch and filter content similar to the PAs used today in the flagship Apple iPhone 7 and Samsung Galaxy S7 will ship in increasing numbers into lower-tier smartphones.

According to Christopher Taylor, author of the report and director, RF & Wireless Components, Strategy Analytics: ”The need for smartphones with more LTE bands has led to multiband PAs that contain more RF filters and switches, capturing more front-end phone content for the suppliers, contributing to a growth of the PA market that will continue at least until 2020 and 5G.”

Eric Higham, Director of Advance Semiconductor Applications at Strategy Analytics, adds: “Gallium arsenide forms the basis of most of the PAs in LTE smartphones, although the PAs now contain more CMOS control, SoI switches and SAW / BAW filter elements than in the past.  As a result of this evolution to multiple die and process technologies in the PA, Skyworks, Qorvo, Broadcom (formerly Avago Tech) and Murata have benefitted, pushing some of the lower-share specialist GaAs PA suppliers such as Mitsubishi and Anadigics out of the market.”
