| Abstract: | Based on the elemental requirements and development of software radio,the paper proposes a design scheme,which is applied to the wide-frequency receiver of frequency hopping radio of software radio,what’s more,the paper analyses whether the secondary mixing scheme of the RF front ends can work or not,and a model of the system is built and verified through simulating.Moreover,different function modules,the filter,the mixer as well as the amplifier of the RF front ends are designed to meet the need of the receiver’s low noise coefficient,good inhibiting of mirroring,the proper gain and right selectivity. |
