13-21 GHz (Ku and K-band) Sub-harmonic Mixer

    Key Features

    • Integrated LO amplifier
    • High isolations
    • Sub-harmonic ×2 LO
    • Single positive supply voltage
    • HMC258 replacement

    Qorvo's CMD303 is a sub-harmonically pumped mixer die with an integrated LO amplifier which can be used as an upconverter or downconverter. The device has low conversion loss and excellent 2LO to RF isolation eliminating the need for additional filtering. The CMD303 requires as low as 0 dBm LO drive and operates on a single positive supply voltage. The sub-harmonic design and low LO drive level allows for less stringent oscillator requirements.
