A Ferromagnetic Resonance Frequency Converter

A frequency converter based on the generation in a ferrite of magnetization at the required difference frequency between input and output signals to provide an alternating environment for the input signal has been operated, and is compared with theory. The principles of the device are those of the amplifier/oscillator proposed by Suhl. Theory and experiment on the converter agree within the expected error of the latter. The support thus provided for the theory is pertinent to the present case and the original amplifier/oscillator.
