Claims (1)

커플러로부터 인가된 고주파 출력 신호를 증폭하는 증폭기와 증폭된 고주파 신호와 중앙처리장치로부터 데이터 신호에 의해 발생된 아날로그스위치의 출력 신호를 비교하는 비교기 및, 상기 비교기의 출력 신호에 의해 동작하여 카폰의 고주파 신호를 제어하는 트랜지스터 어레이를 구비한 카폰의 고주파 출력 제어회로에 있어서; 상기증폭기의 출력 신호에 의해 동작하여 각 로그스텝의 고주파 출력레벨에 대응한 신호를 상기 아날로그 스위치의 각 단자에 인가하여 아날로그 스위치의 출력을 선택하기 위한 제어 수단을 포함하되, 상기의 제어 수단은 상기 고주파 출력 신호가 미세하게 조정될때까지 소정의 신호를 상기 아날로그 스위치의 각 단자에 제공함을 특징으로 하는 카폰의 고주파 출력 자동 제어 회로.An amplifier for amplifying the high frequency output signal applied from the coupler, a comparator for comparing the amplified high frequency signal with the output signal of the analog switch generated by the data signal from the central processing unit, and a high frequency of the car phone operated by the output signal of the comparator A car phone high frequency output control circuit having a transistor array for controlling a signal; And control means for selecting an output of the analog switch by applying a signal corresponding to the high frequency output level of each log step by operating the output signal of the amplifier to each terminal of the analog switch. And a predetermined signal is provided to each terminal of the analog switch until a high frequency output signal is finely adjusted. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
