Tunable capacitors for 4G smartphone PAs

STMicroelectronics has extend the tuning range of its electronically tunable capacitors. Designated the Stptic G2 range, the capacitors now have a 5:1 tuning ratio which means they can add extra correction when signal matching  between a smartphone’s antenna and power amplifier. Other improvements include lower parasitic resistance and…
