Study on the High Speed Frequency Synthesizer with Low Phase Noise for Radar
레이다용 낮은 위상잡음을 갖는 초고속 주파수 합성기에 관한 연구
Abstract
In this paper, frequency synthesizer for radar system is designed and developed. Optimizing the phase noise and lock time, each module is designed as two-type PLL circuit, and then the performance of PLL frequency synthesizer is compared. The experiment result shows the lock time of 70 usec, the phase noise of less then 100 dBc, the bandwidth above 500MHz.
