Paper Abstract

Millimeter Wave Extended Interaction Klystrons manufactured by Varian Canada Inc., since 1969 utilize rectangular resonant cavities with a biperiodic ladder as the interaction circuit. These klystrons are used in radars, communications, scientific instrumentation in the frequency range of 28 to 280 GHz at peak power levels from 1 kW to 5 W, average power levels from 1 kW to 0.5 W . To facilitate the use of these klystrons, power conditioners were introduced in 1983 to combine with the klystrons to form pulsed or CW transmitter subsystems.

In this paper, elementary theory of operation of the EIKs is described, together with design considerations and system interface information. Some historical milestone achievements of the EIK transmitters are summarized. Recent advances are presented, including frequency coverage, output power, bandwidth, gain, noise, size, weight, efficiency, and pulse repetition frequency. Future development of these products are discussed.
