Rugged Amplifiers and Transmitters

FOR RADAR, ELECTRONIC WARFARE AND COMMUNICATIONS

CPI TMD began developing power supplies at the end on the 1980s, expanding its amplifier product line. By leveraging this expertise together with its proficiency in microwave tubes and the complexities of integration, CPI TMD has build a thriving amplifier and transmitter business to serve the needs of its defence and communications customers.

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

CPI TMD’s traveling wave tube amplifiers (TWTAs) and complete transmitters for radar, electronic warfare and communications applications 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 undergo full environmental stress screening (ESS) 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
CPI TMD is developing of multi-tube transmitters to achieve optimum reliability and performance.
