    CPC classification number: H03D7/166

    Abstract: In an embodiment, an apparatus includes a first signal path to receive and process a radio frequency (RF) signal of a first band and which has a first programmable digitizer to convert the RF signal of the first band into a digitized signal without downconversion. In addition, the apparatus further includes a second signal path to receive and process an RF signal of a second band, where at least portions of one or more of the paths may be shared during operation in the different bands.
