本文讨论了１０ＧＨｚ以上频段的数字微波通信系统（特别是中小容量系统）总体设计中的几个特殊问题，如设计参考电路的选择、指标分配、降雨衰减及其对抗措施、高频单元的特殊性和高中频方案、天线的选择、本振配置以及系统备用方式等，并提出自己的观．支和解决办法。 This article discusses several special problems in the overall design of digital microwave communication systems (especially small and medium capacity systems) in the frequency band above 10GHz, such as the design of reference circuit selection, index allocation, rainfall attenuation and countermeasures, the particularity of high frequency unit And high frequency programs, antenna selection, local oscillator configuration and system backup methods, and put forward their own views. Support and solutions.
