1575 MHz 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 ground 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

shown is available from Hittite upon request.
