Functional Diagram
General Description
The HMC349MS8G & HMC349MS8GE are high
isolation 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 +52 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 a single
positive voltage control of 0/+5 Volts at very low DC
currents. An enable input (EN) set to logic high will
put the switch in an “all off” state.
