A Microwave FM Transmitter Locked in Phase for the High Code Rate Telemetry

The microwave FM transmitter locked in phase, which is suitable for 2Mbit/s PCM signal, is the major equipment of the reentrant telemetry system in the 21st century. The key technique of the FM telemetry transmitter, which is quasi-two-point pour way of FM, interrelating circuit designs, and experiment results, are described in this paper. The theoretical analysis and practice indicates that this FM telemetry transmitter has the smooth modulated characteristic in the wide frequency band. It meets practical requirements of transmitting equipment in the telemetry system for the high code rate.
