HARMONIC AND SPURIOUS SIGNAL SUPPRESSION IN MAGNETRONS.
Abstract
An investigation was conducted to determine the causes of spurious output signals from magnetrons. Several corrective measures applied to the RK6344A C-band magnetron resulted in reduction of second and third harmonic output, and of other spurious signals and background noise over a wide frequency range, of 20 to 45 db. Field evaluation of the revised tubes by the Navy confirmed that improved RFI performance had resulted from the design changes. The general characteristics of the spurious signal phenomena, the design techniques developed, and the recommendations for further studies in the field should be of use to magnetron designers in solving RFI problems. Many of the findings will be applicable to other microwave tubes. Utilization of the information already gained, and further pursuit of the field, will lead to fewer electronic interference problems in the field and to increased equipment reliability. (Author)
