Abstract
A low frequency, diode pair mixer is provided in combination with simple, compact transformer circuitry. A diode mixer bridge has a pair of diodes interconnecting secondary windings of single and dual transformers. The diodes are connected in series across the secondary winding of the single transformer. The same polarity ends of the pair of secondary windings of the dual transformer are connected in common to a point between the diodes. The other ends of the pair of secondary windings are connected to respective ends of the secondary winding of the single transformer. The combination affords isolation between the signals coupled through each of the transformers. The combination may be implemented as an up converter or a down converter.
