Abstract

본 발명은 UHF 대역의 원격 제어용으로 사용되는 원격 제어용 송신기에 관한 것으로, 이를 해결하기 위하여 주파수 변조방식으로 디지탈 신호를 변조하는 FSK 변조부와, 기본 주파수를 3배로 체배하는 발진 및 제1체부와, 3배로 체배된 주파수주변의 고주파 성분을 감쇄시키는 제1필터부와, 이 체배된 주파수를 3배로 체배시키는 제2체배부와, 이 체배된 주파수 주변의 고주파 성분을 감쇄시키는 제2필터부와, 이 체배된 주파수를 증폭하는 증폭부와, 이 증폭부에 의해 증폭된 주파수에포함된 고주파 성분을 감쇄시킴과 아울러 소정의 제어신호를 송출하는 제3필터 및 출력부를 포함하도록 구성된다.
