采用ADS软件仿真设计了一种基于GaAs小信号单片微波集成电路(MMIC)、GaN大功率MMIC和多层复合介质板的C波段小型化发射/接收(T/R)模块,实现了微波信号的放大、收发控制、数字幅相控制及+28V高压电源调制的一体化,具有小体积、轻量化、低噪声、高功率、高效率等特点。TR模块尺寸为33mm×65mm×10mm,在C波段实现指标为:发射功率50 W,功率附加效率28%,接收增益37dB,噪声系数3dB。

This paper uses ADS software to simulate and design a C band miniaturization transmit/ receive （T/R） module based on GaAs small signal monolithic microwave integrated circuit （MMIC）, GaN large power MMIC and multilayer composite medium board, which realizes the inte- gration of microwave signal amplification, T/R control, digital magnitude and phase control, high voltage ＋28 V modulation, takes advantage of small volume,light weight,low noise, high power and high efficiency. The size of T/R module is 33 mm× 65 mm× 10 mm,and the module can real- ize： transmitting power 50 W,power additional efficiency 28%,receiving gain 37 dB,noise coeffi- cient 3 dB at C-band.
