SP4T Reflective pHEMT MMIC Switch
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
Electrical Characteristics (at 25C°, [Vctrl 0,+2.7V], 50 Ohm system, under CW )
