Abstract

903,940. Matching impedances. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 1, 1960 [July 21, 1959], No. 23085/60. Class 40 (8). [Also in Group XL (c)] A high-frequency power distributer, e.g. for distributing power from a single source to a number of aerials, comprises an input 10 embodying a fixed impedance transformer and a number of outputs, e.g. 11, 13, whose impedance may be varied by means of eccentrically rotatable inner conductors. The input line 10 feeds the outputs through a radial line 16, 26 to which it is matched by the adjustable capacitance existing between a movable plate 18 and the inner conductor 16 of the radial line. In addition, the inner conductor 23 of the input line comprises two quarter-wave sections 24, 25 of increased radius. The inner conductor of each output line comprises a first quarter-wave section 27 in the form of a segment of a hollow cylinder and a second quarterwave section 28 in the form of a complete cylinder. The sections are rotated eccentrically about the axis of the output line by means of gearing 22.
