Abstract
Embodiments of the present invention may provide a receiver. The receiver may include an RF section and a quadrature mixture, coupled to the RF section, to downconvert a first group of wireless signals directly to baseband frequency quadrature signals and to downconvert a second group of wireless signals to intermediate frequency quadrature signals. The receiver may also include a pair of analog-to-digital converters (ADCs) to convert the downconverted quadrature signals to corresponding digital quadrature signals. Further, the receiver may include a digital section having two paths to perform signal processing on the digital baseband frequency quadrature signals and to downconvert the digital intermediate frequency signals to baseband cancelling a third order harmonic distortion therein. The receiver may be provided on a monolithically integrated circuit.
