Abstract

본 발명은 안테나로부터 입력되는 고주파 신호를 증폭하는 고주파 변조기(RF Modulator)의 부스터단 회로에 관한 것으로, 특히 무전원시 안테나로부터 입력되는 고주파 신호를 텔레비젼(이하) TV의 튜너부로 전달되도록 스위칭부를 구성하여 TV를 제외한 수신기기의 전원이 완전히 오프된 상태에서도 TV 시청이 가능한 무전원시 고주파 신호 전달특성을 가진 고주파 부스터단 회로에 관한 것이다.The present invention relates to a booster stage circuit of an RF modulator for amplifying a high frequency signal input from an antenna. In particular, the switching unit is configured to transmit a high frequency signal input from an antenna to a tuner unit of a television (hereinafter, referred to as “non-powered”). The present invention relates to a high frequency booster stage circuit having a high frequency signal transmission characteristic when a power supply of a receiver other than a TV is completely turned off, so that TV can be viewed.
