| Abstract: | This paper presents a design scheme for a wideband receiver.The rationality of frequency mixing method is ana-lyzed and validated.Then the modeling and simulation of the whole system is proceeded.The results show that this design scheme is correct and effective with high gain of intermediate frequency and more than 90dBc image restraint characteristic. |
