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 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 Hittite upon request.
