FILTER, BANDPASS F-( )/GP
Abstract
Development of an experimental high power S-band spurious harmonic filter, designated as filter, bandpass F-( )/GP, is completed. An experimental model of the filter was built. This filter combines a multiple cavity bandpass filter, a ferrite isolator, a resonant ferrite signal suppressor, and a leaky wall harmonic filter. The composite characteristics of these components provide sharp selectivity, low passband VSWR and insertion loss, high power capacity, and attenuation of the order of 100 db for all frequencies and modes in the reject bands. Advanced techniques investigated during the program included the use of subsidiary ferromagnetic resonances; natural resonances in materials with controlled h-anisotropy and magnetization; and coupled wave techniques for absorbing signals in the reject band. Evaluation of the unit included a test in a resonant ring apparatus at 10 megawatts peak, which the unit passed successfully. (Author)
