A Novel Active Polyphase Filter Employing Frequency-Dependent Image Rejection Enhancement Technique
In low intermediate frequency (low-IF) receivers, image interference rejection is one of the core tasks to be accomplished. Conventional active polyphase filters (APPFs) are unable to have a sufficient image rejection ratio (IRR) at high operating frequencies due to the degradation of the IRR by the...
