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
