Design and Performance of a Multiple-Loop Frequency Synthesizer.
Abstract
The report presents the results of the design and fabrication of a Multiple-Loop Frequency Synthesizer. The design utilizes frequency control loops to extend the capture range of a phase-locked loop used to provide frequency stability. No harmonic generators, mixers, or filters are used, in the usual sense; a single crystal oscillator is required. The synthesizer is small, light weight, accurate to within plus or minus 0.0025% of the programmed frequency, covers the AM broadcast band (500 kHz to 1600 kHz), and is electronically tunable in 10 kHz steps. Unwanted sidebands 5 kHz and 10 kHz away from the programmed frequency have relative magnitudes of -28 db and -40 db, respectively. (Author)
