General Description

SWITCHES - SMT
The HMC349LP4C & HMC349LP4CE are high isolation
non-reflective DC to 4 GHz GaAs MESFET SPDT
switches in low cost leadless surface mount packages.
The switch is ideal for cellular/PCS/3G basestation
applications yielding 60 to 65 dB iso-lation, low 0.9 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.
