This document describes the features and characteristics of the HMC143 and HMC144 chips, which are miniature double-balanced mixers suitable for applications such as microwave point-to-point radios and VSAT. The chips utilize a standard 1um GaAs MESFET process and provide broadband operation and excellent isolation. They are smaller and more reliable replacements for hybrid diode mixers.
The HMC143 and HMC144 are miniature GaAs MMIC double-balanced mixers designed for use as upconverters or downconverters. These devices utilize a standard 1um GaAs MESFET process and feature on-chip baluns that require no external components or DC bias. The HMC144 is identical to the HMC143 except for a mirror-image layout designed to ease integration into image-reject mixer modules.
