Design of a Broadband RF Front End Based on Software Defined Radio(SDR)

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.
