Evaluation Circuit Board
7
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 above. 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 upon request.
