Abstract
A modularization of a circulator and a directional coupler used in a wireless communication system comprises: a circulator; and a signal coupler, where the signal coupler does not have directivity by itself, and directivity of the circulator module is controlled by isolation characteristics of the circulator to improve electrical characteristics of a wireless communication system and miniaturize the wireless communication system by applying the electrical characteristics in common with a circulator to modularize the wireless communication system without implementation of a circuit of a directional coupler capable of sampling high-frequency signals.
