In one embodiment, an analog-to-digital converter (ADC) receives a radio frequency (RF) signal and converts the RF signal into a digital signal at an intermediate frequency. The ADC uses a sampling frequency that is a multiple of the intermediate frequency to perform the conversion. A selector receives the digital signal and outputs a combined in phase and quadrature signal at a plurality of sampling points based on the sampling frequency. A filter receives the combined in phase and quadrature signal and outputs a baseband in phase baseband signal and a baseband quadrature baseband signal.
