Abstract
A frequency‐agile phase lock system for millimeter‐wave klystrons is described. The system locks the klystron to a crystal‐controlled reference signal derived from a frequency synthesizer. By programming the synthesizer, the klystron can be stepped through any sequence of frequencies lying within a band roughly 200 MHz wide. Acquisition of phase lock typically requires 1 msec. The 200‐MHz pull‐in range is achieved through the use of combined frequency and phase feedback; there is no ’’search’’ mode. The measured linewidth of an 82‐GHz phase‐locked klystron is ?10 Hz.Keywords
