A HYBRID RECEIVER ARCHITECTURE USING UPCONVERSION FOLLOWED BY DIRECT DOWNCONVERSION
摘要
<p>A receiver (100) configured to selectively receive an RF signal from an operating band having a plurality of RF channels. The receiver (100) is configured to upconvert (200) the desired RF channel to an intermediate frequency (IF) greater than the RF channel frequencies. The upconverted RF channel is downconverted (230) to baseband or a low IF. The receiver can perform channel selection by filtering (242, 244) the baseband or low IF signal. The baseband or low IF signal can be upconverted to (240) a programmable output IF.</p>
