General Description
The HMC349ALP4CE is a high isolation non-reflective
DC to 4 GHz GaAs MESFET SPDT switch in a low cost
leadless surface mount package. The switch is ideal
for cellular/PCS/3G basestation applications yielding
60 to 65 dB isolation, low 0.9 dB insertion loss and
+53 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.
