Preliminary Data Sheet^1.0
FMS2002 ES1
SP3T Reflective pHEMT MMIC Switch
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
Electrical Characteristics (at 25C°, [Vctrl 0,+2.7V], 50 Ohm system, under CW )
