The power combiner includes a low-pass filter that allows only a predetermined low band to pass therethrough, combines high power signals with a T-Junction structure using a micro strip pattern and outputs only a desired frequency band as a final output signal as the combined signals pass through the low-pass filter. When applying the structure of an embodiment of the present invention, outputs generated at a multi-channel high-power amplifier are combined while passing through the power combiner, and it is possible to use, as a final output, signals from which even harmonic components are cancelled as the combined signals pass through the low-pass filter.

    높은 전력의 신호를 마이크로 스트립 패턴을 이용한 T-Junction 구조로 결합하고, 결합된 신호는 상기 저대역 필터를 거침으로써 원하는 주파수 대역만 최종 출력 신호로 출력하는 것을 특징으로 하는 전력 결합기.And combining the high power signal into a T-Junction structure using a micro strip pattern, and outputting only the desired frequency band as a final output signal by passing through the low band filter.
  2. 제1항에 있어서,The method of claim 1,
    상기 결합된 신호는 저대역 필터를 거치며 증폭기에서 발생되는 2nd 고조파 성분이 제거되어 원하는 주파수 대역(S-band)만 최종 출력 신호로 출력하는 것을 특징으로 하는 전력 결합기.The combined signal passes through a low band filter and removes a 2nd harmonic component generated from an amplifier to output only a desired frequency band (S-band) as a final output signal.
  3. 제2항에 있어서,The method of claim 2,
    T-Junction Combiner가 최종 출력 신호를 결합하는 것을 특징으로 하는 전력 결합기.Power combiner, characterized in that the T-Junction Combiner combines the final output signal.
