摘要
简要介绍毫米波频率合成器的重要性,分析两种毫米波频率合成器实现方案的优劣,综合其优点,并采用直接数字频率合成(DDS)技术,提出毫米波频率合成器的设计方案。进行方案系统实验,结果表明,相位噪声为-85dBc/Hz@10kHz,提升了整个毫米波通信系统的性能。
The importance of millimeter wave frequency synthesizers was introduced briefly, the advantages and disadvantages of two schemes of millimeter wave frequency synthesizers were analyzed, and a final design scheme of millimeter wave frequency synthesizer was put forward by the combination of these advantages and the Direct Digital Synthesis（DDS） technology. A systematic experiment of the scheme was performed, and the results showed that the phase noise was -85 dBc/Hz@10 kHz, which indicated that the performance of the whole millimeter communication system had been improved.
