GENERAL DESCRIPTION

The SGM11124F is a single-pole/four-throw (SP4T)

antenna switch, which supports from 0.1GHz to 6GHz.

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 SGM11124F is not subject

to cellular interference and is applied to multi-mode and

multi-band LTE mobile phones.

The SGM11124F 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 SGM11124F is available in a Green ULGA-1.1×1.1-9L

package.
