RF front end component manufacturers are turning to GaAs as their main material of choice, says TrendForce, while 5G will double the number of components needed compared to 4G. Since the frequencies used for telecommunication between phones in the 4G era have already moved to the 1.8-2.7 GHz range, traditional 3G Si RF front end ...
