[仿真]Prediction of the End-to-End Performance of a Microwave/RF Link

Abstract—This paper describes the simulation of a microwave \ @[Q3.VX  
link from the transmitter to the receiver intermediate-frequency K- $,:28

coupled with the electromagnetic characterization of the 6`vW4]zu  
transmitter and receiver front-ends. This includes a full electromagnetic 4
