General Description
The HMC435MS8G & HMC435MS8GE are non-
reflective DC to 4 GHz GaAs MESFET SPDT switches
in low cost 8 lead MSOP8G surface mount packages
with exposed ground paddles. The switch is ideal
for cellular/PCS/3G basestation applications yielding
50 to 60 dB isolation, low 0.8 dB insertion loss and
+50 dBm input IP3. Power handling is excellent
up through the 3.5 GHz WLL band with the switch
offering a P1dB compression point of +31 dBm. On-
chip circuitry allows positive voltage control of 0/+5
Volts at very low DC currents.
