摘　　要：基于可重构思想,提出了一种适应航空电子综合化设计的宽带射频前端的设计方法。对射频前端的三种架构体制进行比较分析,重点阐述其中的预选器重构、增益重构、放大器的宽频段设计,同时利用ADS软件对其中部分技术指标进行仿真验证。仿真结果表明,该方法设计的射频前端能够满足航空电子综合化需求,可为后续构建一个通用化、标准化、模块化的宽带射频接收前端提供借鉴。Based on the reconfigurable idea, a design method of broadband RF front-end adapting to the integrated avionics design is proposed. The three architectures of RF front-end are compared and analyzed. The pre-selector reconfiguration , gain reconfiguration, and the broadband design of amplifier are emphasized. At the same time, the ADS software is used to simulate and verify some of the technical indexes. The simulation results indicate that the RF front-end designed by the method can meet the comprehensive needs of avionics, and could thus provide a reference for subsequent construction of a universal, standardized and modular broadband RF receiver front-end.
