Abstract
A reconfigurable receiver is disclosed, operating in accordance with a two-step channel selection. The first step provides for a coarse radio frequency (RF) channel selection, to downconvert a desired channel and an image channel of the desired channel to IF. The second step provides for a fine intermediate frequency (IF) channel selection to select either the desired channel or the image channel. The receiver can be used in a transceiver.
