The circuit board used in the final application should use RF circuit design techniques. Signal lines should
have 50 ohm impedance while the package ground leads should be connected directly to the ground plane
similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom
ground planes. The evaluation circuit board as shown is available from Hittite Microwave Corporation upon
request.
