General Description
The HMC349LP4C 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 +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.
