某型多调制方式低相噪毫米波频率源设计
Design of a Multi-Modulation Millimeter Wave Frequency Source with Low Phase Noise Performance
摘要
Abstract
The method of multi-modulation millimeter wave frequency source with low phase noise performance is introduced. DDS and PLL technology as system design and the problem of multi-modulation was solved by FPGA. The digital modulation coding unit was analyzed. The software control process,m sequence of Modelsim simulation results and loop filter design parameter have been presented. The measured results show that modulation signal fre⁃quency center at 30 GHz,output power greater than 4 dBm and phase noise level is better than-100 dBc/Hz at 100 kHz offset frequency.关键词
