SGM72112B

DP12T Diversity Switch

with MIPI RFFE for Carrier Aggregation

GENERAL DESCRIPTION

FEATURES

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.

● Supply Voltage Range: 2.4V to 4.8V

● Advanced Silicon-On-Insulator (SOI) Process

● Frequency Range: 0.1GHz to 3.8GHz

● Low Insertion Loss: 1.0dB (TYP) at 3.8GHz

● MIPI RFFE Interface Compatible

● No External DC Blocking Capacitors Required

● Available in a Green ULGA-2.4×2-18L Package

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.
