Custom MMIC CMD310C3

20-32 GHz (K and Ka-band) Sub-harmonic Mixer

The CMD310C3 is a sub-harmonically pumped mixer die with an integrated LO amplifier housed in a leadless 3×3 mm surface mount QFN package. The CMD310C3 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 CMD310C3 requires only –2 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.
