Abstract
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.
Claims8
A transformer assembly comprising a single core of a magnetic material, said core defining two spaced apertures therein, and two sets of transformer windings, only one set in each of said apertures, wherein one winding of each set emerging from one end of each aperture is interconnected with another winding of the same set emerging from another end of the same aperture.
