This document introduces the HMC256 chip, which is a compact I/Q mixer MMIC that can be used as an image reject mixer or SSB upconverter.
The HMC256 is a compact GaAs MMIC I/Q mixer designed for frequencies from 5.9 to 12 GHz. It features high image rejection of greater than 30 dB and a wideband IF range from DC to 1.5 GHz. The device utilizes two standard Hittite double-balanced mixer cells and a Lange Coupler realized in GaAs MESFET technology.
