Abstract : The limiter program is directed toward the development of a practical microwave limiter for the S- and L-band regions by utilization of the nonlinear, high-power characteristics of ferrites. The design objectives call for a passive broadband device which should provide approximately 60 db of attenuation to high-power signals in the 100 kilowatt range and 1.0 db (or less) loss at low power (less than 75 mw). The areas of investigation were: (1) the effect of the ferrite limiter on the waveshape of the pulsed r-f power, (2) the selection of a suitable ferrite material, (3) the determination of an optimum ferrite-waveguide geometry, and (4) the effect of system environmental conditions on the operation of the ferrite limiter.
