The present invention relates to a device for matching amplifiers by using mutual induction. According to the invention, it provides the device for matching amplifiers by using mutual induction that includes a first conductor connected between a first output terminal of an operating amplifier and a first input terminal of a power amplifier, a second conductor connected between a second output terminal of the operating amplifier and a second input terminal of the power amplifier and in which the opposite current to the first conductor flows, a third conductor forming a coupling with the first conductor by being placed in parallel to the first conductor but in which the opposite current to the first conductor flows and having its end connected to an end of the second conductor, and a fourth conductor forming a coupling with the second conductor by being placed in parallel to the first conductor but in which the opposite current to the second conductor flows, having its end connected to an end of the first conductor, and having the other end connected to the other end of the third conductor. According to the device for matching amplifiers, matching between two terminals can be performed and impedance matching can be performed by placing a plurality of conductors between a power terminal and an operating terminal. In addition, an installation area can be saved by applying it to the inside of a connecting metal between the operating terminal and the power terminal. Moreover, it can be applied to designing a broadband power amplifier because it has a wide operating frequency area. |
