The Design and Operation of Trapatt Diodes for Systems Requirements in the 1-5GHz Frequency Band

Trapatt devices and circuits have been designed for use as solid state transmitters for pulse radars in the l-5GHz range. This has been achieved as a result of a device and circuit investigation in which pulse powers of up to 120 watts with 44% efficiency and mean powers greater than 1 watt have been obtained reproducibly from single diodes at 2.3GHz. An essential part of the work has been to relate real systems requirements to device design and also to device-circuit interactions. As a result of this understanding and the compatibility of the devices with M.I.C. techniques it has been possible to design compact reliable oscillators for the l-5GHz frequency range.
