General Description
Functional Diagram
The HMC322LP4 & HMC322LP4E are broadband
non-reflective GaAs MESFET SP8T switches in low
cost leadless surface mount packages. Covering DC
to 8 GHz, this switch offers high isolation and low insertion loss. This switch also includes an on board binary
decoder circuit which reduces the required logic
control lines to three. The switch operates using a
negative control voltage of 0/-5 volts, and requires a
fixed bias of -5v. This switch is suitable for usage in
50-Ohm or 75-Ohm systems.

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.
