摘要
比较了软件无线电宽带射频前端的几种技术方案特点及其可行性，提出了一种采用多路可配置信道组网射频前端方案，分析了其关键技术及解决措施；并以2—2000MHz宽带射频前端为例进行仿真，给出典型仿真结果，验证了方案的可行性。
Based on the comparison of feature and feasibility of several technical schemes for software defined radio（SDR） broadband RF front end,a novel scheme is proposed which uses multi - way distributive channels RF front end. The key techniques and solutions of this scheme are analyzed. Typical simulation results of a 2 - 2000MHz broadband RF front end are presented as example to validate the feasibility of the scheme.
