Rugged Amplifiers and Transmitters for Radar, EW and Communications

TMD’s amplifier product line came alive after we began developing power supplies at the end of the 1980s, and this together with our understanding of microwave tubes and the complexities of their integration, has resulted in a thriving business.

We have since designed, developed and produced numerous subsystem products for land, air and naval operations, which have gained TMD an international reputation for unmatched performance, excellent reliability and outstanding support.

TMD’s TWTAs or complete transmitters for Radar, EW and Communications have the following features:

  • Fully integrated microwave tube
  • High voltage switched mode power supply
  • Built in test electronics (BITE)
  • Designed for the harshest environments – strong, sturdy, robust, MIL Spec
  • High reliability – all products fully ESS tested before shipment
  • High level of customer support worldwide
  • High level of product innovation – TMD won a Queen’s Award for innovation in 2005 for a low noise radar power supply design

We are currently working on the development of multi-tube transmitters to achieve optimum reliability & performance.
