SGM11108E数据手册SGMICRO中文资料规格书

描述 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.
