MXD8650 DP4T Switch for 3G/4G and Diversity Application
General Description
MXD8650 is a general purpose DP4T for 3G/4G
and diversity application.
The device is processed in advanced CMOS
silicon-on-insulator (SOI) technology featuring low
insertion loss, high isolation, high linearity and
high ESD protection level. The excellent
performance makes it ideal to be applied in
application for 3G/4G multi-mode WCDMA, UMTS,
and LTE.
The MXD8650 is packaged in small, ultra-thin, 10
pins, 0.4mm pitch (1.1 x 1.5 x 0.45 mm) package.
Features

Frequency Range : 0.1 ~ 3.0 GHz
Low Control Voltage : 1.6 ~ 3.3 V
Low Insertion Loss : 0.4 dB at 2.7 GHz
High Isolation : 20 dB at 3.0 GHz
RoHS / Halogen Free Compliant
Moisture Sensitivity Level : MSL-1
Applications
Cellular Handset Applications
Cellular Modems and USB devices
