Abstract: Limiting amplifier module is a common module in microwave system. With the development of microwave technology and the improvement of the transmitting power of microwave system, the system puts forward higher and higher requirements for the bearable power of the limiting amplifier module. When the maximum power that a single limiter can bear fails to meet the requirements of the system demands, the input high power signal is divided into several limiters by the way of power division, so as to meet the requirements of the system demands. In this way, we have developed a number of limiting amplifier modules, including C-Band 500 W limiting amplifier module, Ku-Band 100 W limiting amplifier module and Ka-Band 16 W limiting amplifier module, which were respectively applied in multiple microwave transceiver systems.
