SP3T Reflective pHEMT MMIC Switch
FMS2002 ES1
Description

The FMS2002 is a linear high power Single-Pole Three-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 three RF ports
.
Features
Low insertion loss (0.5dB @ 900 MHz)
Operation down to 2V control
3 control lines. Single positive voltage supply
Low harmonics (Typical -73dBc at Pin=+34.5dBm)
High Isolation (30 dB @ 900 MHz)
Filtronic Advanced GaAs pHEMT Technology
