CMD282C3

DC-22 GHz (L, S, C, X, Ku, K Band) 2-bit Digital Attenuator

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.
