Abstract

621,386. Electric resonators; frequency stabilization. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 26, 1946, No. 6030. Convention date, Feb. 26, 1945. Drawings to Specification. [Class 40 (viii)] Ultra-high frequency, such as that of a magnetron generator, is stabilized by means of an anti-resonant circuit, one limb of which comprises a relatively low impedance of high Q, obtained by transforming a higher impedance of lower Q by means of a length of waveguide or the like. The drawings are similar to Figs. 1 to 17 and 26 of Specification 621,385, less the parts relating to modulation means, and the Specification discusses mathematically the optimum conditions for stabilizing frequency.
