Overview
The HMC329A-SX, produced by Analog Devices Inc., is a high-performance, general-purpose, double-balanced mixer. This GaAs MMIC (Monolithic Microwave Integrated Circuit) is designed to operate as either an upconverter or downconverter within the frequency range of 22 GHz to 38 GHz. The mixer is characterized by its small size, measuring 0.87 mm × 0.58 mm, and does not require any external components or matching circuitry. It features excellent local oscillation (LO) to radio frequency (RF) and LO to intermediate frequency (IF) suppression due to optimized balun structures. The device operates with LO drive levels at 13 dBm or above, making it suitable for various high-frequency applications.
