v00.0403

1 dB LSB GaAs MMIC 3-BIT DIGITAL

POSITIVE CONTROL ATTENUATOR, 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 circuit board shown is available from Hittite upon request.
