11.8GHz低相噪频率源的设计
Design of 11.8 GHz low phase noise frequency synthesizer
摘要
Abstract
Low phase noise frequency synthesizer plays an important role in radar system. A 11. 8 GHz low phase noise frequency synthesizer is designed for automotive anti-collision radar. Based on the study of phase locked-loop CPLL) , the possibility for the implement of low phase noise is analysed, the design of the phase frequency detector, the VCO and the loop-filter is also introduced. The test result of the 11. 8 GHz frequency synthesizer shows low phase noise is below —90 dBc/Hz at 1 kHz. The other results also reach intended targets. The 11. 8 GHz low phase noise frequency synthesizer enhances the performance of the automotive anti-collision radar.关键词
