Description

UHF 튜너에 있어서의 발전기와 믹서의 공용회로Shared circuit of generator and mixer in UHF tuner

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 사용되는 회로계통의 일예도,1 is an example of a circuit system used in the present invention,

제2도는 제1도와 같은 계통에서 발전기와 믹서를 별도로 분리하여 이용되어온 상태를 예시하는 참고도.2 is a reference diagram illustrating a state in which the generator and the mixer are separately used in the same system as in FIG.

Claims (1)

UHF 튜너의 단간동조회로 출력단에 연결되는 믹서겸 증폭회로와 발진회로의 독립된 연결 구성을 가지는 것에 있어서, 상기믹서겸 증폭회로와 발진회로를 하나의 트랜지스터(Q3)의 입력측으로 궤환되는 그 출력측의 발전형성부(1A)와 상기 출력측으로부터 IF 신호를 IF 검파단으로 보내는 제1코일(L1)과의 관련구성으로 된 것을 특징으로 하는 UHF 튜너에 있어서의 발진기와 믹서의 공용회로.In the independent connection configuration of the mixer and amplifying circuit and the oscillating circuit connected to the output stage of the inter-tuning circuit of the UHF tuner, the output side of which the mixer and amplifying circuit and the oscillating circuit are fed back to the input side of one transistor Q 3 . A common circuit of an oscillator and a mixer in a UHF tuner, characterized in that the power generation unit (1A) and the first coil (L 1 ) send an IF signal from the output side to the IF detector. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
