Abstract
PURPOSE:To improve high-electric-power resisting and temperature characteristics of a lumped constant type circulator with three terminals, etc., by attaining a low loss, broad band and miniaturization by loading a capacitor except floating capacity between the ground and a connection point between a capacitor and inductor. CONSTITUTION:With regard to a lumped constant type circulator with three terminals A, B and C having three-peak characteristics, series circuits of capacitor CS1 and inductor LS1 in the above order from terminal sides to center conductors (a), (b) and (c) of the circulator are constituted, the series circuits are connected between terminals and center conductors respectively and capacitors CP2 except floating capacitor are also interposed between the ground and connection points between capacitors CS1 and inductors LS1. Consequently, the miniaturization, reduction in loss and broad band of the unit can be attained, so that high-electric- power resistant characteristics and temperature resistant characteristics can be improved.
