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.
Electrical Specifications, T_A = +25° C, Vctl = 0/+5 Vdc, Vdd = +5 Vdc, 50 Ohm System
