Abstract
A low frequency diode mixer is provided in combination with simple, compact transformer circuitry. A four diode mixer interconnects three dual transformers. The mixer has a pair of separate, isolated two diode sections commonly servicing the first transformer and separately servicing the other two transformers.
Claims5
A frequency converter comprising, in combination:
- first, second and third dual transformers, each having a primary winding and a pair of secondary windings;
- and
- a four diode mixer, comprising a first and second isolated two diode sections, interconnecting said secondary windings for heterodyne modulation product signal generation, the first diode section comprises a first pair of diodes interconnecting the first secondary winding of said first transformer and the secondary windings of said second transformer, and the second diode section comprises a second pair of diodes interconnecting the secondary winding of said first transformer and the secondary windings of said third transformer.
