Functional Diagram
General Description
The HMC345LP3 & HMC345LP3E are broadband
non-reflective GaAs MESFET SP4T 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 two. The switch operates using a
positive control voltage of 0/+5V, and requires a fixed
bias of +5V.

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.
