| Abstract: | With the development of communication technology, the change range of communication frequency has become wider and wider. To realize the steadiness of output frequency and phase with low energy consumption in the phase-locked loop system for GSM solar repeater, this paper tells of the phase-locked loop principle, analyzes the phase locked loop system of GSM solar repeater, and describes the specific design and application of the circuit. Test on the phase-locked loop system, indicate that this system could meet the performance requirements of repeater output frequency synthesizer. |
| Keywords: | phase-locked loop（PPL） frequency synthesizer solar repeater |
