The paper introduces the design and key technologies of an S-band high power T/R module. The T/R module has four channels, and is complex in function and structure. It contains four transmitting channels and twelve receiving channels, which can meet the requirement in practical application for multi-channel receiving. The twelve received signals are combined to 3 output ports by using 3 different 1 ∶ 4 dividers, and the dividers are simulated to optimize the circuit. The output power of each transmitting channel is more than 100 W, with over 40% efficiency. The receiving gain flatness value and the maximum receiving gain difference are all less than 1 dB for all the 12 channels. Since lots of chips and packing devices are used, technical flow is also briefly introduced. The mod?ule test results show that it meets the specification requirements.
