A Novel Surface Acoustic Wave Synthesizer for FH-SS Systems |

| Abstract: | A novel synthesizer designed for frequency-hopping spread spectrum (FH-SS) communication system with respect to the injection mode selection principle of multimode surface acoustic wave (SAW) oscillators is reported by this paper. Its operation principle and working procedure are first set forth in the very different way. The synthesizer has the properties of fast frequency hopping speed, high frequency stability , simple and compact structure, powerful pro-grammability,small volume, light weight and saving electronic power,etc. So it is fit for the situ-ations where require high performance frequency sources, such as tactics frequency-hopping transceivers .signal sources for measurements, other civil mobile frequency-hopping transceivers, and so on. |
