GENERAL DEscriptION

The SGM72322A is a double-pole/double-throw (DPDT) switch, which supports from 0.4GHz to 3.8GHz. The device features low insertion loss and high isolation, which make it suitable for high linearity and 2G/3G/4G applications.

The SGM72322A has the ability to integrate DPDT RF switch and GPIO controller on an SOI chip. Internal driver and decoder for switch control signals are offered by the GPIO controller, which makes it flexible in RF path routing and band selection.

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 SGM72322A is available in a Green UTQFN-2×2-12AL package.
