Method and system for a dual mode receiver with low intermediate frequency (IF) and zero second IF

摘要

In RF transceivers, a method and system for a dual mode receiver with low intermediate frequency (IF) and zero second IF are provided. An RF receivers may be adapted to operate in a low IF down conversion mode or a baseband down conversion mode. A control signal may be generated based on a local oscillator signal and may be utilized to configure a frequency mixer in accordance with the selected mode of operation. The frequency of the local oscillator may be based on the low IF value. When the low IF down conversion mode is selected, the frequency mixer operates in a pass through mode and the output may be transferred to a device with a low IF interface. When the baseband down conversion mode is selected, the output of the frequency mixer may be transferred to a baseband processor for further processing.
