水下个人语音通信系统发射机研制

In this paper, a new type of transmitter circuit for underwater voice communication system based on analysis of its working principle is presented. The transmitter has the outstanding advantages of high efficiency, strong anti-jamming capability, and miniaturization. The transmitter circuit consists of photoelectric coupled circuit transmission system, class-D audio power amplifier, the matching circuits and transducer. The experimental study has been made in the anechoic tank. Test results show that the circuit design is correct, the components are matching reasonably. The design has superior performance and has achieved the system requirements.
