How to combat the many causes of radio sensitivity degradation

Zero-IF (homodyne) receivers are an increasingly popular form of radio receiver, offering several notable advantages over older and more complex architectures.

But zero-IF receivers suffer from degradation of sensitivity for a wide variety of reasons. Armed with knowledge of the causes of such degradation, design engineers will be well equipped to take counter-measures, and ensure their circuit enjoys reliable radio reception and adequate range.

This article provides a description of the main mechanisms that cause sensitivity degradation in zero-IF receivers, and suggests techniques and components that help the developer to combat their effects.
