GaAs MMIC VOLTAGE-VARIABLE

ATTENUATOR, 5 - 26.5 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 con-

nected 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.
