Microwave Frequency Memory,

Abstract

This memorandum is concerned with a frequency memory system which has an unlimited storage time. Such a system was built, having a set-on accuracy to within 10 MHz in a bandwidth of 500 MHz minimum, for a single RF input pulse of 100 nsec duration or greater. To achieve this performance, two multimode oscillators (MMOs) were combined. One of these oscillators has a coarse set-on accuracy in a wide band, whilst the other had a finer set-on accuracy in a narrower band. Several theoretical accounts of MMO behavior are contained in the literature 1, 2, 3. Essentially the memory is achieved by setting an oscillator close to the frequency of an input signal, such that the oscillator remains on that frequency when the input signal is removed. (Author)
