Multi Standard Reconfigurable Receiver Architecture for Wireless Systems

The existence of a large number of wireless standards motivates the investigation of a multi-standard wireless receiver architecture that uses the same hardware in meeting performance requirements. This paper presents an architecture of a reconfigurable receiver operating in both Low-IF and Zero-IF modes for GSM-1800 and UMTS-2100 wireless standards. The reconfigurability in the RF front-end part is achieved by a reconfigurable filter based on a dual mode resonator with the possibility of using MEMS switches to tune the center frequency and the bandwidth of the preselect filter. System-level analysis and derivation of block-level specification for the specified standards are developed to design the receiver. Simulation results for both system-level analysis of the reconfigurable receiver and circuit design of the reconfigurable filter are presented and discussed.
