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 backside ground slug 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 avail-

able from Hittite upon request.
