STUDY OF PULSED RADIATION EFFECTS ON MICROWAVE FERRITE DUPLEXERS
Abstract
The results from the second series of radiation environment experiments are presented. These experiments were performed to substantiate and extend the data on the duplexer components' behavior obtained during the first series of experiments. Data are also presented from preliminary investigations of the radiation effects in waveguide elements and static dc voltage experiments which were conducted to simulate possible high microwave power electric field intensities. Briefly described and reviewed are procedures for testing the coaxial ferrite Y-junction circulator, the gyromagnetic coupling limiter, the internal magnetic coaxial isolator and C-band waveguide elements at a micro wave power of 100 mw in the frequency range of 5.4 to 5.9 gc. Also reviewed is the method used to perform the static dc voltage experiments involving tests of the microwave components mentioned above, various open-ended connectors and short pieces of open-ended cable. Photo graphs of oscilloscope traces showing radiation effects on the operating characteristics of the microwave components and leakage characteristics of the components used in the dc experiments are presented. Quantitative interpretations of the data obtained by circuit calibration procedures are also presented. Results of dosimetry provided by the SPRF are tabulated along with the radiation effects noted in the components investigated in each experiment.
