18-40 GHz (K, Ka Band) Voltage-Variable Attenuator MMIC

    Key Features

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

    Qorvo's CMD172 is a wideband, RF / Microwave GaAs MMIC absorptive Voltage-Variable Attenuator (VVA) die which operates from 18 to 40 GHz. The VVA uses a single DC control voltage of -3V to 0V to control RF signal levels over a 37 dB dynamic range. The CMD172 attenuator MMIC has an extremely low insertion loss of 1.6 dB and is a 50 ohm matched design which eliminates the need for RF port matching. The CMD172 also offers full passivation for increased reliability and moisture protection.
