Abstract

The rapid development of software defined radio made stringent requirements for wideband receivers to be wide operating frequency, effective with frequency selectivity, low noise factor, high sensitivity and wide dynamirange. This paper presents a design scheme for wideband receiver in the software defined radio broadcasting stations. The nationality of three frequency mixings method is analyzed and validated. Then the modeling and simulation of the whole system is proceeded. The results show that this design scheme´s each target are superior to the requirements of the existing software-defined radio RF front-end.
