General Description
The HMC336MS8G is a broadband non-refl ec­tive GaAs MESFET SPDT switch in a low cost 8 lead MSOP8G surface mount package with an exposed ground paddle. Covering DC to 6.0 GHz, this switch offers high isolation and low insertion loss. The switch operates using a positive control voltage of 0/+5 Volts, and requires a fi xed bias of +5V. This switch is suitable for usage in 50-Ohm or 75-Ohm systems.

The circuit board used in the fi nal 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.
