TMD Technologies Limited (TMD) is one of the World's leading designers of microwave tubes, high voltage power supplies and subsystems for radar, EW, communications, EMC and RF testing, medical and laboratory applications. 

Our origins can be traced back to the high power klystron group of EMI, involved with the development of the first airborne radars during the 1940s. Since then, as part of EMI and later THORN, the company has been responsible for many of the major technical advances in the industry. 

In the last 20 years we have radically enhanced our expertise in switched mode power supply and microwave subsystem design.
