GENERAL DESCRIPTION

The SGM11124E is a single-pole/four-throw (SP4T)

antenna switch, which supports from 0.1GHz to 3GHz.

The device features low insertion loss and high

isolation, which make it suitable for high linearity

receiving and 2G/3G/4G transmitting/receiving (TRx)

applications. It also has the advantage of high linearity

performance. The SGM11124E is not subject to cellular

interference and is applied to multi-mode and multi-band

LTE mobile phones.

The SGM11124E has the ability to integrate SP4T 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 SGM11124E is available in a Green ULGA-1.1×1.1-9L

package.
