VARIABLE GAIN AMPLIFIER

17 - 27 GHz

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 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 circuit board shown is available from Hit-

tite upon request.
