Evaluation PCB
The circuit board used in the 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 board
should be mounted to an appropriate heat sink. The
evaluation circuit board shown is available from
Hittite upon request.
