120586 Evaluation PCB

[1] Reference this number when ordering complete evaluation PCB

[2] Circuit Board Material: Rogers 4350.

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 appro-

priate heat sink. The evaluation circuit board shown

is available from Hittite upon request.
