DEVELOPMENT OF AN E-BAND AMPLIFIER
Abstract
Progress is reported on the tunable filter and the design of the tube's permanent magnet. An electromagnet for testing the tube and filter was built and tested. Wide gap fields to 2.5 times the design estimate with 4% uniformity over the gap are available for tube focusing. In the short gap mode of peration this electromagnet provides over 30,000 gauss, sufficient for operation of the millimeter wave filter. A test structure for the YIG crystals was fabricate . This structure should allow separate testing o the crystal itself for Q to determine the expected optimum performance of the filter with the material on hand. Comparison with actual filter performance will thus allow separation of the effect of miscellaneous waveguide losses and reflections. (Author)
