Evaluation PCB
The circuit board used in the  nal application
should use RF circuit design techniques. Signal
lines should have 50 Ohm impedance while the
package ground leads and package bottom 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.
