HMIC Manufacturing

High-Reliability Microwave Integrated Circuits for Mission-Critical Applications

Overview

Ananth offers advanced Hybrid Microwave Integrated Circuit (HMIC) manufacturing services designed for high-performance RF, microwave, and millimetre-wave applications. With decades of experience supporting missile seekers, radar front-ends, satellite payload electronics, and EW systems, we deliver HMIC modules that meet the most demanding specifications.

Our HMIC facility integrates precision engineering, specialised material handling, and stringent MIL/space-grade processes to produce miniaturized, rugged, and high-performance microwave assemblies.
