摘要
针对卫星通信工作频率越来越高的应用需求,设计了一种工作在极高频(Extremely High Frequency,EHF)的接收模块,实现极高频射频信号的接收及下变频功能。模块内部集成波导-微带探针过渡、低噪声放大器、微带滤波器、本振电路、混频器及供电电路,具有低噪声系数、高增益、高带外抑制的优点。采用单片微波集成电路(Monolithic Microwave Integrated Circuit,MMIC)混合多功能集成技术实现了模块的小型化、通用化,可适应多种场景下的极高频收发前端应用,具有广阔的应用前景。
In response to the increasing demand for higher operating frequencies of satellite communication,a receiver operating in Extremely High Frequency(EHF)band which realized RF receive and down-conversion function is designed.The receiver includes waveguide-microstrip probe transition,low noise amplifier,microstrip filter,local oscillator circuits,mixer and feed circuits.The advantages of the receiver are low noise figure,high gain and high out-of-band rejection.The receiver also utilizes Monolithic Microwave Integrated Circuit(MMIC)hybrid multifunctional integration technology to realize miniaturization and universalization,making it suitable for different EHF band transceiver front-end application with broad application prospects.
