This document describes the features and characteristics of the HMC338 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, including the integrated LO amplifier, high 2LO/RF isolation, and small size.
The HMC338 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 26 to 33 GHz frequency range and utilizes PHEMT technology for a small chip area.
