General Description
The HMC849LP4CE is a high isolation non-reflec-
tive DC to 6 GHz GaAs pHEMT SPDT switch in a low
cost leadless surface mount package. The switch is
ideal for cellular/WiMAX/4G Infrastructure applicati-
ons yielding up to 60 dB isolation, low 0.8 dB inser-
tion loss and +52 dBm input IP3. Power handling
is excellent up through the 5 - 6 GHz WiMAX band
with the switch offering a P1dB compression point of
+31 dBm. On-chip circuitry allows a single positive
voltage control of 0/+3V or 0/+5V at very low DC
currents. An enable input (EN) set to logic high will put
the switch in an “all off” state.
