GENERAL DEscriptION

The SGM72003 is a single-pole/triple-throw (SP3T) antenna switch, which supports from 0.1GHz to 3GHz. The device features low insertion loss and high isolation, which makes it suitable for high linearity receiving application. It also has the advantage of high linearity performance. The SGM72003 is not subject to cellular interference and is applied to multi-mode and multi-band LTE mobile phones.

The SGM72003 has the ability to integrate SP3T 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 band and routing 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 SGM72003 is available in a Green UT×1.1-9L package.
