Evaluation PCB

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 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 Hittite upon

request.
