An integrated wideband-IF-receiver architecture for mobile terminals

A wideband-IF receiver architecture is described for use in mobile terminals capable of receiving multiple standards´ like GSM, UMTS, DECT, etc. The architecture uses a single down-conversion and digitizes the wanted signal at high intermediate frequencies. The wideband nature of the architecture ensures a great adaptability to various mobile standards. It denotes a step in the direction of a fully reconfigurable software radio due to the shift of the ADC to higher frequencies. The paper is focused on the realization of the analog part of the receiver.
