Abstract

본 발명은 통신기기의 자동송신출력 조절장치에 관한 것이다.The present invention relates to an automatic transmission output control apparatus of a communication device.

종래 통신기기의 송신출력 조절장치는 연속성을 갖지 않는 하이 및 로우상태로 조절하므로서, 연속적으로 조절되는 방식보다는 전체적으로 소모전류가 많게 되는 문제점이 있었다.The transmission output control device of the conventional communication device has a problem in that the current consumption is increased as a whole, rather than continuously controlled by adjusting the high and low state does not have continuity.

따라서 본 발명은 상기한 종래기술의 문제점을 개선코자 하여 수신부의 동작레벨설정을 다이오드를 이용하여 기준전압을 설정하고 동작범위를 연산증폭기의 이득을 조절하여 범위를 설정하므로서, 수신전계강도가 높은 근거리 통화시 송신출력을 자동으로 조절함에 따라 소모전류가 감소되어 밧데리 사용시간을 연장시킬뿐만 아니라, 타무선전화기와의 간섭영향도 감소시키도록 한 것이다.Therefore, the present invention is to improve the above-mentioned problems of the prior art by setting a reference voltage using a diode to set the operation level of the receiver using a diode and the operating range by adjusting the gain of the operational amplifier, thereby establishing a near field high in intensity. By automatically adjusting the transmission power during a call, the current consumption is reduced, which not only prolongs the battery usage time but also reduces the influence of interference with other wireless telephones.
