General Description
The HMC922LP4E is a DC to 4 GHz high isolation
GaAs MMIC non-reflective Differential SPDT switch
in a low cost leadless surface mount package. The
switch is ideal for antenna diversity & selector selec-
tion, broadband switch matrices, test & measurement
equipment, military and space applications yielding
up to 60 dB isolation, low 0.8 dB insertion loss and
+50 dBm input IP3. Power handling is excellent with
the switch offering a P1dB compression point of
+35 dBm. On-chip circuitry allows two positive voltage
controls of 0/+3V to 0/+5V at very low DC currents.
