DC-40 GHz (L, S, C, X, Ku, K, Ka Band) 2-bit Digital Attenuator

    Key Features

    • Ultra wideband performance
    • Low insertion loss
    • Wide attenuation range
    • Small die size

    Qorvo's CMD282 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 4 dB and 8 dB, for a total attenuation of 12 dB. The CMD282 has a low insertion loss of 1.5 dB at 18 GHz and the attenuation accuracy is typically 0.1 dB step error. The CMD282 is a 50 ohm matched design which eliminates the need for RF port matching. The CMD282 offers full passivation for increased reliability and moisture protection.
