The CMD281 is negative controlled, wideband GaAs MMIC 2-bit digital attenuator die which operates from DC to 40 GHz. Each bit of the attenuator is controlled by a single voltage of either 0 V or –5 V. The attenuator bit values are 2 dB and 4 dB, for a total attenuation of 6 dB. The CMD281 has a low insertion loss of 1.2 dB at 18 GHz and the attenuation accuracy is typically 0.1 dB step error. The CMD281 is a 50 ohm matched design which eliminates the need for RF port matching. The CMD281 offers full passivation for increased reliability and moisture protection.
