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.
