Abstract
PURPOSE:To obtain a distributing and coupling circuit which has simple, small- sized constitution and excellent electric characteristics, by connecting the inputs of trailing in-phase output type hybrid circuits to the outputs of leading stages, and connecting a 90 deg. phase circuit to one output of each final stage. CONSTITUTION:A three-stage distributing circuit is constituted by connecting Wilkinson type hybrid circuits H31-H37 of a two-distribution in-phase output type which each consist of strip lines SL1 and SL2 having length g/4 and characteristic impedance 2<1/2>Z0, and an absorbing resistance 2R having a resistance value double as great as characteristic impedance Z0. Then, 90 deg. phase circuits P1-P4 are connected to one-side outputs of hybrid circuits H34-H37 as final stages. An input signal applied to a terminal TIN is divided into eight and sent out to respective output terminals T01-T08; reflected waves from respective output terminals are absorbed by absorbing resistances 2R in the hybrid circuits H34-H37 and never reach the input terminal TIN.
