SP4T Reflective pHEMT MMIC Switch
FMS2003 ES1
Description

The FMS2003 is a linear high power Single-Pole Four-Throw
MMIC Antenna Switch designed for use in Dual-band
handsets GSM900 and GSM1800/1900 combinations. The
switch is designed with one antenna port that can be routed
to any one of the four RF ports
.
Features
Low insertion loss (0.5 dB @ 900 MHz)
Operation down to 2V
4 control lines. Single positive voltage supply
Low harmonics (Typical -67dBc at Pin=+34.5dBm)
High Isolation (30 dB @ 900 MHz)
Filtronic Advanced GaAs pHEMT Technology
