General Description
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
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.

The circuit board used in the final application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should have
50 ohm impedance and the package ground leads
and backside ground slug should be connected
directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is
available from Hittite Microwave Corporation upon
request.
