Claims (2)
- 무선단말기의 전력 소모량 절감 장치에 있어서,수신되는 신호의 증폭도를 조절하여 출력하는 저잡음증폭기와,인가되는 증폭도 제어신호의 상태에 따라 바이어스 전류값을 가변하여 상기 저잡음증폭기의 신호 증폭도를 조절하는 가변바이어스부와,인가되는 증폭도 제어신호의 상태에 따라 입력 신호와 발진주파수의 혼합 상태를 조절하여 출력하는 가변 혼합부와,수신전계 강도의 세기를 판단하고, 그 결과에 따라 증폭도 제어신호를 구분하여 출력하는 제어부를 더 구비함으로서 수신 전계의 상태에 따라 전력 소모량을 절감하는 장치.
- 제1항에 있어서, 상기 제어부는,수신전계 강도의 세기가 일정 전계이상의 강전계인 경우, 상기 가변바이어스부와 상기 가변혼합부로 인가되는 전류가 감소되도록 처리함으로서 수신 전계의 상태에 따라 전력 소모량을 절감하는 장치.
