Ferrite frequency doubling from 9 to 18 kmc. By and John Alan Mehrten and John Alan Mehrten. Topics: Ferrites (Magnetic materials) Publisher: The University of Arizona. Year: OAI identifier: oai: Provided by: The.   Simultaneous measurements have been made of the absorption at kMc and of the second harmonic magnetization generated in single crystal Zn 2 Y. The high planar anisotropy of this ferrite enhances its frequency doubling behavior. The results agree well with the predictions of the equation of motion for the magnetization with anisotropy and losses by: 3.   A high intensity microwave magnetic field and an orthogonal dc magnetic field were applied to a ferrite body. Double frequency magnetic fields were generated in the same direction as the dc magnetizing field. A primary frequency of mc was used with peak powers up to watts. The peak output power at mc was found to increase linearly Cited by: A ferrite frequency doubler in the microwave range with a conversion efficiency of 5% to an external second harmonic load, for an input power of w, is described. The design of this to 17 Gc converter is based upon theoretical and experimental work reported earlier.

  Theoretically, the ideal ferrite would provide a high impedance at the EMI frequencies, and zero impedance at all other frequencies. In reality, ferrite suppresser cores provide a frequency dependent impedance. Low at frequencies below 1 MHz, and depending upon the ferrite material the maximum impedance can be obtained between 10 MHz to MHz.

Since ferrite cores used in low signal level and power applications are concerned with magnetic parameters below this frequency, rarely does the ferrite manufacturer publish data for permeability and/or losses at higher frequencies. However, higher frequency data is essential when specifying ferrite cores used in the suppression of EMI. RFI and Ferrites Jim Brown K9YC Audio Systems Group, Inc.
