With the continuous progress and development of science and technology in our country, the rapid development of microwave communication system has promoted the forward progress of our country's communication industry. In the microwave communication system, the transmitter is one of the most critical equipment, which has a critical impact on the quality and efficiency of communication. In order to ensure the sustainable and stable development of the whole microwave communication system and to transmit stable signals, more efforts should be put into the development and application of transmitter technology. This paper mainly analyzes the transmitter technology of microwave communication, which can provide a certain reference for subsequent applications.展开更多

The specific circuit and measured results of some key modules in transmitter are presented, and some outdoor experimental tests have been carried out, which shows that the completed prototype of transmitter can generate a continuous sine current with frequency up to 35.33 k Hz, peak-to-peak amplitude up to 40 A, and realize a reliable transmitting mode with multi-frequency and high-current. The transmitter has a wide operating band, large magnetic moment and high waveform fidelity, and can meet the requirements of shallow geological exploration with high-resolution.展开更多
