Abstract
A low frequency, diode quad mixer is provided in combination with simple, compact transformer circuitry. A diode quad mixer bridge interconnects the secondary winding of a single transformer and the four secondary windings of a pair of dual transformers. The combination affords isolation between the signals coupled through each of the transformers, and may be implemented as an up converter or a down converter.
