Claims (1)

UHF/VHF올 밴드수신용 튜너에 있어서, UHF부 혼합단과 VHF부 혼합단과를 결합하는 U-V결합용 스윗칭 다이오드의 음극을 고저항을 개재하여서 VHF부 RF 증폭단의 밴드 절환용스윗칭다이오드의 양극측에 접속하고, UHF수신시에 VHF부 RF증폭단의 로우밴드수신용 코일을 고주파적으로 단락하도록한 것을 특징으로하는 튜너.In the UHF / VHF all-band receiving tuner, the anode side of the band switching switching diode of the VHF RF amplifying stage via the high resistance of the cathode of the UV coupling switching diode which combines the UHF mixing end and the VHF mixing end. And a low-band receiving coil of the VHF unit RF amplifier stage at high frequency short circuit at the time of UHF reception. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
