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 and exposed paddle 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 board should be mounted to an

appropriate heat sink. The evaluation circuit board

shown is available from Hittite upon request.
