108535 Evaluation PCB
[1] Reference this number when ordering complete evlaution 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.
