This article introduces the characteristics, performance and working principle of the high-speed-rate phase-locked demodulator, the core equipment of telemetry ground station newly developed by our factory. In the foreword, the basis for developing a high-code-rate phase-locked demodulator, the direction of the development of the telemetry video, and the conclusion of the research are described. Then, the performance characteristics of the high code-rate phase-locked demodulator are introduced. , Frame structure and so on ...) and the test results of the main technical indicators. Finally, the working principle and design basis of the high code rate phase locked demodulator are introduced. The main parameters of the high speed phase locked loop are tested and verified whether Meet the use of telemetry project requirements.
