Evaluation PCB

The circuit board used in the final application

should be generated with proper RF circuit design

techniques. Signal lines at the RF ports should be

50 ohm impedance and the package ground leads

and package bottom should be connected directly

to the PCB RF ground plane, similar to that shown

above. The evaluation circuit board shown above is

available from Hittite Microwave Corporation upon

request.
