The SGM72004B is a single-pole/four-throw (SP4T) antenna switch, which supports from 0.1GHz to 3GHz. The device features low insertion loss and high isolation, which make it suitable for diversity reception applications. It also has the advantage of high linearity performance. The SGM72004B is not subject to cellular interference and is applied to multi-mode and multi-band LTE mobile phones.

The SGM72004B has the ability to integrate SP4T RF switch and GPIO controller on a SOI chip. Internal driver and decoder for switch control signals are offered by the GPIO controller, which makes it flexible in RF path band and routing selection.

No external blocking capacitor requirements on the RF paths as long as no external DC voltage is applied which can save PCB area and cost.

The SGM72004B is available in a Green UTQFN-2×2-14L package.
