General Description
The HMC435MS8G is a non-reflective DC to 4
GHz GaAs MESFET SPDT switch in a low cost
8 lead MSOP8G surface mount package with an
exposed ground paddle. The switch is ideal for
cellular/PCS/3G basestation applications yielding
50 to 60 dB isolation, low 0.8 dB insertion loss and
+50 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 positive voltage control of
0/+5 Volts at very low DC currents.

List of Material
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 imped-
ance 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.
