Abstract

PURPOSE:To simplify circuit constitution by constituting a series circuit in the order of an inductor and capacitor toward a center conductor and then by loading a capacitor between the inductor-capacitor connection point and the earth. CONSTITUTION:From the terminal sides to center conductors (a), (b) and (c) of the circulator, series circuits are constituted respectively in the order of inductor LS1 and capacitor CS1 and while the series circuits are connected between the terminals and center conductors respectively, capacitors CP2 other than a floating capacitor are loaded between the earth and connection points between inductors LS1 and capacitors CS1 respectively. Further, a resistor is connected between the earth and one of terminals A, B and C.
