| Abstract: | Based on the basis requirements and developing trend of software defined radio(SDR),a circuit structure of receiver RF front-end is proposed for the receiver of SDR-based frequency-hopping(FH) radio.The system design scheme of the receiver RF front-end is analysed,including distribution and calculation of every part′s gain and dynamic rang,and computation of noise figure and sensitivity.Consideration of selecting devices is discussed.Test result indicates the RF front-end meets the design requirements. |

| Keywords: | software defined radio FH radio receiver RF front-end sensitivity noise figure dynamic rang |
