Abstract
A method and device for adjacent channels operation based on downconverting the input signal to an IF signal, filtering the IF signal, and upconverting the filtered IF signal to the original frequency. The present invention is primarily directed to applications involving the use of standard RF transceiver which does not incorporate a high Q filter. Moreover, the present invention may be used with a circular polarized cross recessed corners stacked array antenna in order to further improve its adjacent channels operation performance.
