Abstract

644,410. Electric resonators. PHILIPS ELECTRICAL, Ltd. Feb. 11, 1948, No. 4019. Convention date, Feb. 14, 1947. Drawings to Specification. [Class 40 (viii)] The perpendicular cross-section of a cavity resonator in the form of a rectangular prism is a parallelogram with an angle of 45 degrees and sides in the ratio 1: #2. This gives a higher Q for a given height and operating frequency than a cylindrical resonator or one of square cross section.
