Product Overview

The CMD282C3 is a negative controlled, wideband GaAs

MMIC 2-bit digital attenuator housed in a leadless 3x3 mm

surface mount package. Each bit of the attenuator is

controlled by a single voltage of either 0 V or

–5 V. The

attenuator bit values are 4 dB and 8 dB, for a total

attenuation of 12 dB. The CMD282C3 has a low insertion

loss of 1.9 dB at 10 GHz and the attenuation accuracy is

typically 0.2 dB step error. The CMD282C3 is a 50 ohm

matched design which eliminates the need for RF port

matching.
