InGaP HBT GAIN BLOCK

MMIC AMPLIFIER, DC - 6.0 GHz

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 board should be

mounted to an appropriate heat sink. The evaluation cir-

cuit board shown is available from Hittite upon request.
