The RF front end (RFFE) has become an increasingly challenging component of the mobile ecosystem with the advent of 5G, because of the wide variety of spectrum bands, and aggregated band combinations, that may be supported. Developers of RFFE – which sits between the antenna and the modem – have to support maximum flexibility so that devices can support a range of bands without each combination needing to be separately designed and manufactured. They also have to do this while minimizing power consumption, cost and footprint, all of which could potentially be increased by 5G. But this is no longer just about smartphones and high value devices, or even just about 5G. The growth in units, if not margins,…
