The circuit board used in this application should use RF
circuit design techniques. Signal lines should have 50
ohm impedance while the package ground leads and
exposed paddle 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 board should be mounted
to an appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
