HMC339 is a GaAs MMIC SUB-HARMONICALLY PUMPED MIXER from Hittite Microwave Corporation. It works in the frequency range of 33 - 42 GHz and has an integrated LO amplifier. It can be used as an upconverter or downconverter. This chip uses GaAs PHEMT technology, which results in a small overall chip area of 1.07mm2. The 2LO to RF isolation is excellent, eliminating the need for additional filtering.
The HMC339 is a GaAs MMIC sub-harmonically pumped (x2) mixer with an integrated LO amplifier, designed for use as an upconverter or downconverter in microwave radio and satellite communication systems. It operates in the 33 to 42 GHz frequency range and utilizes PHEMT technology to achieve a small chip area of 1.07mm².
