Evaluation PCB - Option 1 Application

The circuit board used in the final application

should use rf circuit design techniques. signal

lines should have 75 ohm impedance while the

package ground leads and package bottom 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 board should be mounted

to an appropriate heat sink. The evaluation circuit

board shown is available from Hittite upon request.
