Abstract
[목적] 송신필터가 대역내 편차나 VSWR을 갖는 것이라도, 출력파워가 주파수 특성을 갖지 못하게 한다.
[구성] 출력파워를 검출하는 출력파워 검출수단(17)을 송수신필터(13)보다 후단에 설치하여, 출력파워의 제어루프(17),(18),(13)를 동작시키도록 하였다. 예를 들면, 출력파워 검출수단(17)을, 분파회로(14) 내의 송신 전송로나, 분파회로(14) 및 안테나(16)을 잇는 고주파 전송로(15)에 삽입시킨다.

Claims (4)
- 송신신호를 파워앰프를 통하여 전력증폭한 후, 송신필터에 의해서 송신대역에 제한하여 안테나로부터 송신시키는 이동체 통신장치에 설치된 출력파워 제어회로로서, 출력파워를 검출하는 출력파워 검출수단과, 검출된 출력파워가 기준치로 되도록 파워앰프의 게인을 제어하는 자동파워 제어회로를 갖는 출력파워 제어회로에 있어서, 출력파워 검출수단을 송신필터 보다 후단에 설치한 것을 특징으로 하는 이동체 통신장치의 출력파워 제어회로.
- 제1항에 있어서, 상기 이동체 통신장치가 송수신 가능한 것이며, 상기 안테나와 송신계 및 수신계의 접속을 나눠 놓은 분파회로내의 송신전송로에 상기 출력파워 검출수단을 설치한 것을 특징으로 하는 이동체 통신장치의 출력파워 제어회로.
- 상기 이동체 통신장치가 송수신 가능한 것이며, 상기 안테나와 송신계 및 수신계의 접속을 나눠 놓는 분파회로와, 상기 안테나를 잇는 전송로에 상기 출력파워 검출수단을 설치한 것을 특징으로 하는 이동체 통신장치의 출력파워 제어회로.
- 송수공용 안테나로 보내는 송신신호의 대역을 제한하는 송신필터와, 상기 송수공용 안테나가 보족한 신호로부터 수신신호의 대역성분을 꺼내는 수신필터와 상기 송신필터 및 상시 수신필터와, 상기 송수공용 안테나의 전송로를 나눠 놓은 분파회로를 갖는 공중선 공융기에 있어서, 상기 분파회로내의 송신전송로에, 송신신호의 출력파워를 검출하는 출력파워 검출수단을 설치한 것을 특징으로 하는 공중선 공용기.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
