| Abstract: |
| 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. |
| Key words: software defined radio(SDR),broadband RF front end,IF bandpass sampling |
