0.5dB LSB GaAs MMIC 6-BIT DIGITAL
ATTENUATOR, DC - 13 GHz
Evaluation PCB
The circuit board used in the 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 eval-
uation circuit board shown is available from Analog
Devices upon request.
