Background
With the development of the radio frequency power amplifier industry, especially the rapid development of electromagnetic compatibility, the solid-state power amplifier has an increasing power output requirement. Due to the power limitation of the single module of the solid-state power amplifier, a high-power synthesis system is necessary to obtain higher-power output, but in the high-power synthesis system, the phenomena of complex wiring and messy wiring often appear in the aspect of power supply. In the high-power synthesis system, the control of the system to all modules is theoretically the control relationship of a pair of multipath modules, so that the problems of limited control ports and mutual interference often occur in the multipath signal processing aspect. Aiming at the problems, a power supply and communication integration module of a power amplification system is introduced, and the power supply and communication integration module has the advantages that: firstly, the power supply circuit is clear; the interior of the module can be designed again according to the requirement; solving the problem of mismatching of the branch ports of the power supply port bus; fourthly, integrating and reporting the working states of various modules; the requirement on the hardware of the main control module is low; taking an S-band 15kw power amplifier as an example, there are 12 power amplifier modules in total. In the traditional system, the internal design mode is that all modules are powered and the communication system is wired in a one-to-many corresponding connection mode, as shown in fig. 1, at this time, 12 power supply cables are needed on a circuit, and a "power supply unit" needs to provide 12 groups of power supply interfaces, so that it is difficult to make 12 groups of power supply interfaces on an equipment panel, and the attractiveness of the whole system is affected. In terms of communication, a communication bus port "master unit" needs 12 corresponding DB9 communication ports, and the realization of the communication bus port "master unit" on a practical panel can cause the communication ports of the master unit to be too many and difficult to realize. Therefore, a high-power pulse power amplifier synthesis system with a power supply and communication integration unit and a power supply and communication integration module is needed to be developed.
