A HYBRID RECEIVER ARCHITECTURE USING UPCONVERSION FOLLOWED BY DIRECT DOWNCONVERSION

摘要

A receiver (100) configured to selectively receive an RF signal from anoperating band having a plurality of RF channels. The receiver (100) isconfigured to upconvert (200) the desired RF channel to an intermediatefrequency (IF) greater than the RF channel frequencies. The upconverted RFchannel is downconverted (230) to baseband or a low IF. The receiver canperform channel selection by filtering (242, 244) the baseband or low IFsignal. The baseband or low IF signal can be upconverted to (240) aprogrammable output IF.
