     本文首先简单介绍了功率管放大器的工作状态、输入输出阻抗特性及各种阻抗匹配网络的设计;讨论了功率管放大器电路的稳定性、最大增益和输出功率等问题;利用功率放大器的CAD仿真软件ADS对高频地波雷达发射机放大电路进行优化设计。根据雷达系统要求,研究固态发射机的组成,完成了600W全固态发射机各级功放电路的设计和调试,对末级功放电路进行优化设计与仿真,同时对发射机进行了散热设计。研究了2KW功放模块的设计方案,并利用小信号S参数设计法设计了第二级功放电路,对其进行了ADS仿真和电路优化。论文还设计了基于CPLD的发射机控制保护电路,可以对射频输入、驻波、电压和温度等状态信息进行检测和保护发射机。该发射机已应用于某雷达试验系统,并取得了较好的试验结果。
Combined with some scientific research project, this paper studies the problems related to the full solid-state transmitter used in a kind of HF ground wave radar.
     Firstly, this paper introduces the operational state of the power amplifier, the input and output impedance characteristic and the design of impedance matching networks. The stabilization, maximum gain and output power of the power tube amplifier is also discussed. And the circuit optimization utilizing the CAD software ADS is formulated. Based on the requirement of the radar system, this paper presents the structure of solid-state transmitter, and the power-amplifying circuits at each stage for the 600W solid-state transmitter are designed and debugged. An analysis is made of the design optimization and simulation for the final power amplifier circuit. Meanwhile, the study on heat dissipation of power amplifier is performed. A design scheme of the 2KW power amplifier module is presented. The circuit of the second stage power amplifier is designed by using the method of small-signal S parameters as well as simulated and optimized using the ADS software. At last, the control system with CPLD is designed, which can detect the input of RF, standing wave, voltage and temperature and protect the transmitter. The transmitter designed has been successfully applied to the experimental system for a type of HF ground wave radar with satisfying results.
