Thomas J. Russell

In 1975 Russell founded KRYTAR, a privately owned company that specializes in the manufacture of ultra broadband microwave components and test equipment for space, military and commercial usage. Russell developed one of the first computer-aided engineering (CAE) tools specifically for the design of microwave couplers. This software was used for the design and development of several of the company's early patented product lines.

After graduation, he joined Douglas Aircraft Company in Santa Monica and then moved on to Bendix Aviation in Kansas City and joined Alfred Electronics in Palo Alto in 1966, before starting his own company nine years later.

Russell’s first patent was filed in 1966. During his career he filed 8 separate patents, spanning four decades, all related to directional couplers and similar technologies. In 1979 he received a patent based upon the idea of increasing the directivity of a coupler by building the central couplers in a unique configuration for a TEM mode strip-line directional coupler. By making the end portion immediately adjacent and in between the diverging conductors facing the coupling portion, thus increasing the directivity of TEM mode strip-line directional couplers which decreases cost.

Thomas J. Russell (born June 13, 1933) was an American engineer and businessman. He was one of the early pioneers of microwave technology, specializing in ultrabroadband microwave directional couplers. Due to his contributions in shaping the microwave industry with innovation and invention, Thomas J. Russell was officially named a Microwave Legend in 2006.
