GENERAL DESCRIPTION

The SGM11108E is a single-pole/eight-throw (SP8T)

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

The device features low insertion loss and high

isolation, which make it suitable for 2G/3G/4G

transmitting/receiving (TRx) applications. It also has the

advantage of high linearity performance. The SGM11108E

is not subject to cellular interference and is applied to

multi-mode and multi-band LTE mobile phones.

The SGM11108E has the ability to integrate SP8T 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 SGM11108E is available in a Green UTQFN-2×2-14L

package.
