Temperature compensation methods employed throughout the study program are briefly reviewed. Satisfactory temperature compensation has not been achieved. Several coupling structures were successfully designed permitting low loss coupling to the input and output resonators. A satisfactory tuning method has also been devised. The results of this program show that a band-pass filter employing dielectric resonators is practical to build, is compact, and approaches the performance of an equivalent waveguide filter. The design presented employs five resonators mounted in a cylindrical tube which is 1.4 inch diameter by 4.3 inches long and weighs 4.6 ounces. An equivalent waveguide filter would be approximately 2.3 x 4.5 x 16 inches long and weigh approximately 64 ounces WR-430. Author
