| Abstract: |
| Based on the basis requirements and developing trend of software defined radio(S
DR), a circuit structure of receiver RF front-end is proposed for the receiver o
f 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.Consid
eration of selecting devices is discussed.Test result indicates the RF front-en
d meets the design requirements. |
| Key words: software defined radio FH radio receiver RF front-end sensitivity noise figure dynamic rang |
