Double balanced mixer using single ferrite core

摘要

Disclosed is a double balanced mixer using a novel single ferrite core construction. The core includes two apertures and a transformer is wound through each aperture. The two transformers are connected by diodes in the known manner to provide the mixer. The arrangement lends itself to simple construction and provides a mixer which is smaller than heretofore possible and which exhibits exceptional high frequency response and flatness with satisfactory isolation.
