A Radio Frequency mixer is a three-port passive or active device that combines two or more signals into one or two composite output signals, and is the backbone of heterodyne and superheterodyne communications technologies. The purpose of a mixer is to produce a signal at a new frequency, while preserving other characteristics of the initial ..

Introduction to Mixers A microwave frequency mixer is a 3-port electronic circuit that combines two or more signals into one or two composite output signals, and are categorized as switching mixers or nonlinear mixers– although many mixers are configured with both. Using diodes, the mixer is passive and has a conversion loss. Using active devices, ..
