The SGM72204A is a single-pole/four-throw (SP4T) antenna tuning switch. The device features low on-resistance and turn-off capacitance, high linearity, low insertion loss and high RF voltage handling capability, which has a very significant improvement effect on TRP and TIS. The SGM72204A is a GPIO interface product based on SOI process, allowing customers to flexibly use its control interface to improve product performance. No external DC blocking capacitors required on the RF paths as long as no external DC voltage is applied, which can save PCB area and cost. The SGM72204A is available in a Green UTQFN-1.1× 1.5-10L package.
