General Description
The HMC321LP4 & HMC321LP4E are broadband nonreflective 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 positive
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.
