Abstract
PURPOSE: To constitute the circulator with transistor circuits etc., by locating the non-reciprocity circuit having two openings as an element circuit so that it has a given directivity and by sequentially connecting the element circuits sequentially with power distributor.
CONSTITUTION: Three isolators 11,12,13 consisting of transistors etc. are located to a given direction, and three power distributors 21,22,23 are inserted among them. The scattering matrix of the isolator is as expressed in equation (I), and the power distributor is of Wilkinson type and its scattering matrix is taken as eqation (II). However, |α1|2+|α2|2≤1. The overall scattering matrix is expressed as equation (III) from the equations(I) and (II). From the type of S matrix, the circulator which has perfect matching at each port and the isolation is also complete and the amount of transmission is α1α2U, can be obtained. Further, the circulator with three opeings can be obtained by connecting the external of the three opening circulator constituted with the non-reciprocity circuit having two openings as element circuit to the six opening reactance compensation circuit.
