Abstract
A receiver for a multi-mode wireless device is provided. The receiver has multiple analog RF front end modules, with each module supporting a different mode of operation. The receiver has a single digital backend module for generating a digital baseband signal. A controller selects one of the available RF modules to use, and the selected RF module provides an analog communication signal to the digital backend. Each available mode has an associated set of factors. When a particular mode is selected, the set of factors associated with the selected mode is provided to the digital backend. The digital backend uses these factors to adjust the processing characteristics of its components, such as its analog to digital converter, filters, and gain controller. In this way, the single digital backend is adaptable to the requirements of each of the available radio modes.
