Study of the Frequency Synthesizer in FH Radio Based on CMOS Chip

Abstract:

The frequency hopping (FH) communication is one of the anti-interference effective means in military wireless communication, the FH number and FH rate of FH radio are the main parameters that determines the performance of the FH radio, these parameters are determined by the structure and the index of the frequency synthesizer, therefore the performance of the FH radio depends very much on the frequency synthesizer, this paper introduces the basic principle of FH radio, the basic methods of frequency synthesizer in the radio, the design scheme frequency synthesizer, and the DDS CMOS chip and the PLL CMOS chip that those used in scheme.
