Abstract

An ultra fast frequency agile local oscillator with high spectral purity is presented. It can be used in a queuing channelized receiver to generate the required local oscillator frequency for each newly received pulse within the pulse duration. It can also be used as a local oscillator in pulse-to-pulse frequency agile radars with high pulse repetition frequencies. The time necessary to change the oscillator frequency is that of the output electronic switch. The phase noise and the frequency stability are those of the crystal oscillator. The spectral purity is guaranteed by the proper filter design.
