The system-level design and simulation of RF front-end in airborn ultra-short wave receiver

Abstract： In this paper, according to the needs of airborn ultra-short wave receiver, the system-level design and simulation of RF front-end circuit is carried out by using Advanced Design System（ADS）. By analyzing the performance requirements of ultra-short wave receiver, combined with the main working principle and technical indicators of the receiver, the structure of the dual-conversion superheterodyne receiver is selected as the implementation scheme. The system level simulation model of RF front-end of receiver is established in ADS. The key indicators of RF front-end of the design such as noise figure, sensitivity, gain and intermodulation distortion are designed, analyzed and simulated by ADS. The simulation results show that the RF front-end meets the requirements of the design.
