GENERAL DEscriptION

The SGM72112B is a dual single-pole/six-throw (2×SP6T) antenna switch, which supports from 0.1GHz to 3.8GHz. The device features low insertion loss and high isolation, which make it suitable for high linearity receiving applications. It also has the advantage of high linearity performance for diversity receiving in carrier aggregation applications. The SGM72112B has the ability to integrate a DP12T (2×SP6T) RF switch and a programmable MIPI controller

on silicon-on-insulator (SOI) process. Internal driver and decoder for switch control signals are offered by the controller, which makes it flexible in RF path band and routing selection.

No external DC blocking capacitors are required on the RF paths as long as no external DC voltage is applied, which can save PCB area and cost.

The SGM72112B is available in a Green ULGA-2.4×2-18L package.
