SWITCHES - SMT
The circuit board used in the final 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 above. A sufficient number of VIA holes should be used to connect the top and
bottom ground planes. The evaluation circuit board as shown above is available from Hittite Microwave Corpora-
tion upon request.
