Abstract

667,290. Wave-guides. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 23, 1950 [March 4, 1949], No. 6035/49. Class 40 (viii). A microwave circuit arrangement having a number of input and output connections between certain of which power can pass without affecting other connections comprises a number of rectangular wave-guide sections supporting H 01 modes connected at spaced points to a section of circular guide supporting a H 11 mode. In the first construction a fourarm bridge arrangement is shown. Power is fed from two sources into input guides 1 and 2 respectively, the latter being arranged at right angles. By the transformer action of their junctions with circular guide 5, each gives rise to a H 11 wave in guide 5 polarized at right angles to the axis of its corresponding rectangular guide. Two output guides 3 and 4 positioned at right angles are provided and, by a suitable choice of the angle # between the two pairs of guides, the resultant wave in guide 5 is coupled to one output guide and does not affect the other. An application to an attenuator is shown in Fig. 2. Power passes from an input guide 11 to output guides 17 and 18 through two circular guides joined by a rotatable rectangular guide 14. This latter varies the plane of polarization of the wave in guide 16 and thus varies the ratio in which the power is divided between guides 17 and 18. One of these is connected to a dummy load and the other provides a variable output. Specification 654,906 is referred to.
