| Preliminary Data Sheet 1.0 FMS2003 ES1 FMS2003 ES1 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 (at 25C, [Vctrl 0,+2.7V], 50 Ohm system, under CW ) Condition Min.
