STUDY OF INTERACTION STRUCTURES LEADING TO DEVELOPMENT OF X-BAND CROSSED-FIELD AMPLIFIER.
Abstract
Research concerns development of an X-band crossed-field amplifier having a delay ratio of 20 in the center of the band, in order to insure the attainment of the necessary 7- to 11- KMCS bandwidth. Further, the line must be capable of dissipating 3 to 4 kilowatts of power, which it will be called on to handle in order to be useful in a crossed-field amplifier tube giving 2 kilowatts of CW power. The line which was studied for this requirement is a multiple meander line, which is called a fenced line. S-band fenced lines were constructed on ceramic by photoforming techniques. An S-band fenced line was constructed having a delay ratio of 20 and a pitch about 3 times smaller than the initial photoformed lines. The dispersive characteristics of this line were measured and tests to determine its other characteristics are continuing. In addition, construction of an X-band line, scaled from the S-band line, was started, using photoforming techniques developed as another portion of the study. (Author)
