Abstract: A radio receiver for receiving signals of at least two different communication standards, including a narrow band signal having a narrow bandwidth and a wide band signal having a wide bandwidth, is provided. The receiver comprises a shared radio frequency (RF) front-end that receives the wide band signal during at least one period of operation, downconverts, in a single downconversion, the wide band signal directly to baseband, receives the narrow band signal during at least another period of operation, and downconverts, in a single downconversion, the narrow band signal to a low intermediate frequency (Low-IF). The receiver further comprises a baseband processing chain that operates on the downconverted wide band signal to extract desired data and a Low-IF processing chain that operates on the downconverted narrow band signal to extract desired data.
