Problems solved by technology
[0002] The shortwave transceiver integrated radio frequency module is one of the key parts of the software radio communication platform. In the traditional shortwave channel unit, due to the use of a custom bus, the scalability is poor, and it can only realize the receiving and excitation functions of a single channel, which has low applicability. , and in data transmission and information exchange, the data transmission speed is relatively slow, it is difficult to meet the needs of the growing short-wave communication

Provided is a four-channel short wave receiving and sending unit based on an Ethernet bus. The four-channel short wave receiving and sending unit comprises a master control module, a frequency synthesis module, a front panel module, a power supply module, four receiving and sending integrated radio frequency modules and four channel modulation-demodulation modules. The frequency synthesis module is used for providing a clock signal to each channel modulation-demodulation module. The receiving and sending integrated radio frequency modules are used for processing the received short wave radio frequency signals so that intermediate frequency signals are generated. The master control module is connected with the frequency synthesis module, the front panel module, the four receiving and sending integrated radio frequency modules and the four channel modulation-demodulation modules in a signal connection way via the Ethernet bus. The master control module is coordinated with the front panel module so that operation and control towards the short wave receiving and sending unit are realized. Integration of receiving and stimulation of four short wave channels is realized by the four-channel short wave receiving and sending unit so that number and weight of short wave channel units in a large-scale short wave communication system can be reduced and size is reduced. Besides, the four-channel short wave receiving and sending unit is high in expandability, high in transmission rate and great in anti-interference performance.
