Abstract
Description
Claims (2)
- (정정) 안테나를 통하여 수신된 VHF대역의 RF신호를 UHF대역신호를 변화함에 있어 고정발진주파수신호를 발생하는 국부발진부와, 상기 입력된 VHF RF신호와 고정발진주파수신호를 혼합시켜 UHF대역신호를 발생하는 혼합부와, 2개의 다이오드를 포함하되, UHF 대역 선택시는 그 UHF 대역신호를 상기 2개의 다이오드 중 어느 한 다이오드를 통해 통과시키고, VHF 대역선택시는 상기 혼합부로부터 출력된 UHF 대역신호를 나머지 다이오드를 통해 출력시키는 VHF/UHF 대역 절환스위치부와, 상기 VHF/UHF 대역 절환스위치부를 통해 입력된 UHF 대역신호와 소정의 국부발진주파수를 혼합하여 중간주파수신호를 발생하는 UHF튜너부를 구비한 것을 특징으로 하는 텔레비젼수상기의 튜너장치.
