ON TESTS WITH LIKELIHOOD RATIO CRITERIA IN SOME PROBLEMS OF MULTIVARIATE ANALYSIS
Abstract
The design and low-power performance are presented for a high-power L-band filer, utilizing 3 direct-coupled TE 011 resonators. The filter is tunable from 1250 to 1350 mc and has a midband insertion loss varying from 0.14 to 0.32 db. The 3-db insertion loss bandwidth varies from 2.86-3.51 mc. The 60-db-insertion-loss bandwidth varies from 14.5 to 19 mc. The coupling apertures in the filter are rounded so that their theoretical power-handling capacity is greater than that of filter cavities. The theoretical midband power-handling capacity of the filter operating at atmospheric pressure is abou 2 megawatts. At approximately the 1/2-db-insertion-loss points, at the edges of the pass band, the power-handling capacity has a minimum value of approximately 1 megawatt at atmospheric pressure. If this filter is operated at a gauge pressure of about 30 psi, its power-handling capacity is theoretically increased by a factor of 9 and hence its theoretical maximum powerhandling capacity is increased to 9 megawatts.
