Functional Diagram
General Description
The HMC231G7 is a broadband high isolation nonreflective GaAs MESFET SPST switch in a hermetic surface mount package. Covering DC to 6 GHz, the switch features >55 dB isolation up to 2 GHz and >42 dB isolation up to 6 GHz. The switch operates using complementary negative control voltage logic lines of -5/0V and requires no bias supply. When the “OFF” state is selected, both RF1 and RF2 ports are terminated in 50 Ohms.

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 package bottom 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.
