Abstract
본 발명은 소정의 제어신호에 의해 발진주파수가 가변되는 국부발진기와, 상기 국부발진기의 출력과 안테나에 수시되어 증폭된 VHF 및 UHF 대의 RF 신호를 혼합하는 혼합기와, 상기 혼합기에서 증폭된 신호를 입력으로 하여 선국된 VHF 및 UHF 대 채널의 중간주파수를 출력하는 IF 동조부로 이루어져 하나의 혼합기와 국부발진기 및 IF 동조회로를 사용하여 안테나에 수신된 RF 신호중에서 VHF 와 UHF 신호를 선국하는 튜너에 관한 것이다.The present invention provides a local oscillator whose oscillation frequency is varied by a predetermined control signal, a mixer for mixing the output of the local oscillator and the RF signals of the VHF and UHF bands received and amplified by the antenna, and the signals amplified by the mixer. The present invention relates to a tuner for tuning a VHF and UHF signal among RF signals received at an antenna by using a mixer, a local oscillator, and an IF tuning circuit. .
