SGM72112A

SP12T LTE Switch with MIPI RFFE Interface

GENERAL DESCRIPTION

FEATURES

The SGM72112A is a single-pole/twelve-throw (SP12T)

antenna switch, which supports from 0.1GHz to 3.0GHz.

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. The SGM72112A is not subject

to cellular interference and is applied to multi-mode and

multi-band LTE mobile phones.

● Supply Voltage Range: 2.4V to 4.8V

● Advanced Silicon-On-Insulator (SOI) Process

● Frequency Range: 0.1GHz to 3.0GHz

● Low Insertion Loss: 0.75dB (TYP) at 2.7GHz

● MIPI RFFE Interface Compatible

● No External DC Blocking Capacitors Required

● Available in a Green UTQFN-2.5×2.5-20L Package

BLOCK DIAGRAM

The SGM72112A has the ability to integrate SP12T RF

switch and 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.

MIPI RFFE Interface

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.
