Abstract

본 발명은 종래의 각각 별개로 구성된 FM 튜너 인쇄회로기판과 AM 튜너 인쇄회로기판 및 주변 회로부를 단일의 인쇄회로기판에 통합 구성하므로서 연결부위의 불량을 제거하고, 조립공정의 단순화와 세트의 소형화함을 고안의 목적으로 하는 FM/AM일체형 튜너에 관한 것이다.The present invention integrates the conventional FM tuner printed circuit board, AM tuner printed circuit board, and peripheral circuit parts into a single printed circuit board to eliminate defects in the connection part, simplifying the assembly process, and miniaturizing the set. The present invention relates to an FM / AM integrated tuner.
