FMS2001 ES1
Low Loss SPDT Reflective pHEMT MMIC Switch
Description
The FMS2001 is a low loss linear Single-Pole Double-Throw Antenna Switch
designed for use in mobile handset applications. The switch is designed with
one antenna port that can be routed to any one of the two RF ports.
Features
· Low insertion loss (0.6dB @ 900 MHz)
· Operation down to 2V control
· 2 control lines. Single positive voltage supply
· Low harmonics (Typical -68dBc 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 )
