Abstract

본원 발명은 오픈스터브(open stub) 및 쇼트스터브(short stub)를 이용하여 증폭된 고조파성분을 억압하는 증폭기에 관한 것으로서, 증폭부와, 입력신호를 상기 증폭부에 최대로 전달하기 위한 입력 정합회로부와, 상기 증폭부에 구동전원을 공급하는 바이어스공급부와, 상기 증폭부의 출력단에 연결되어 증폭된 신호 중에 포함된 고조파 세력을 억압하는 쇼트스터브(short stub) 및 오픈스터브(open stub)와, 고조파세력이 억압이 신호를 출력단에 최대로 전달하는 출력 정합회로부로 구성되어 쇼트스터브에서 우수고조파를 억압하고, 오픈스터브에서 기수고조파를 억압함으로써 높은 주파수대역에서 사용이 가능하고, 회로구성이 간단하여 소형화할 수 있는 것을 특징으로 한다.The present invention relates to an amplifier for suppressing harmonic components amplified by using an open stub and a short stub, and includes an amplifier and an input matching circuit for maximally transferring an input signal to the amplifier. A bias supply unit for supplying driving power to the amplification unit, a short stub and an open stub for suppressing harmonic forces included in the amplified signal connected to an output terminal of the amplifying unit, and a harmonic force This suppression is composed of an output matching circuit unit that transmits the signal to the output terminal to the maximum level. It suppresses even harmonics in the short stub and suppresses odd harmonics in the open stub, so that it can be used in a high frequency band and the circuit configuration is simple and miniaturized. Characterized in that it can.
