TMD Technologies Limited (TMD) is among the world’s leading manufacturers of microwave tubes, high voltage power supplies, and transmitters for Radar, EW, Communications, EMC RF testing, and other Laboratory applications.

TMD can trace its roots back to the early 1940’s, when the microwave tube research division of EMI Electronics was established to develop high power klystrons, for use in the first airborne radars being developed during the Second World War.
