Design of Solid-state Transmitter for Some HF Ground-wave Radar

According to the demand for the full solid-state transmitter in some high frequency ground-wave radar, it mainly discusses the design of the core parts of the transmitter, which are the power amplifier module as well the control and protection system. It presents a method to optimize the design of power amplifier module, some aspects related with both the final power amplifier circuits and the matching designs are also discussed. Then, the operating principle of control and protection system is analyzed. With the control logic design of CPLD, the logic synthesis and timing analysis are completed. The test results indicate that the performance of power amplifier module is up to our requirement, and the control and protection system shows good performance in controlling and protecting the transmitter with great flexibility and adaptability
