根据声表面波（ＳＡＷ）多模振荡器注入选模原理设计了一种用于跳频扩谱通信系统（ＦＨ－ＳＳ）的新型频率合成器，并首次以新的观点阐述了它的工作原理和工作过程。所设计的跳频频率合成器具有跳变速度快、稳定度高、结构简单紧凑、可编程能力强、体积小、重量轻、耗电少等特点，适用于各种要求高质量频率源的场合，如战术跳频电台、测量用信号源以及各种民用移动跳频电台等。 A novel frequency synthesizer for frequency-hopping spread-spectrum communication system (FH-SS) is designed according to the principle of SAW injection and mode selection. For the first time, a new viewpoint is given on how it works And work process. The design of frequency hopping frequency synthesizer with jumping speed, high stability, simple and compact structure, programmable, small size, light weight, low power consumption, suitable for a variety of applications requiring high-quality frequency of the occasion , Such as tactical frequency hopping radio, measurement signal source and a variety of civil mobile frequency hopping radio.
