Microwave Engineering Corporation originally named Microwave Research Corporation, was founded in 1968 as a custom design and manufacturing company providing state-of-the-art components, transmission lines and precision test equipment for microwave and communication systems. MEC is one of the original developers of broad band, high power devices, which gained worldwide preeminence in modern EW, ECM and Communication systems. Our product lines cover the spectrum from 0.1 to 100 GHz in various media including rectangular, ridged and circular waveguide, both rigid and flexible; coaxial transmission lines; stripline and antennas. Due to MEC's prominent position and know-how, we have also provided many of our customers with R&D, system design, theoretical studies, field-installation and technical consulting. In 1992, MEC acquired Datron's Tech Systems, also known as Technicraft in Thomaston, Connecticut. Tech Systems was a leading supplier of waveguide assemblies for the military and commercial markets, specializing in flexible waveguide including seamless, twistable and side seam. MEC continues to fabricate, support and expand all of Technicraft's products. On May 31, 2002 MEC acquired SierraCom, a division of Sierra Networks, Inc. They developed and manufactured a broad array of passive microwave components and subsystems for the United States military. Significant customers include the Department of Defense, as well as leading defense OEMs such as BAE, Lockheed Martin, Northrop Grumman and Raytheon.
