Abstract

A reconfigurable receiver, a reconfigurable transmitter and a multimode receiver are disclosed, operating in accordance with a two-step channel selection. In the receiver, 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. In the transmitter, the first step provides for a fine channel selection and upconversion of a desired channel to either positive or negative IF. The second step is a coarse channel selection and upconversion of a desired channel to the RF. The receiver and transmitter can be used in a transceiver.
