Evaluation PCB

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 con-

nected 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 shown is available from Hittite upon request.
