High-frequency amplifier circuit for UHF television tuner having less distortion |
摘要 |
A high-frequency amplifier circuit for a UHF television tuner includes an FET having a first gate for inputting a UHF band television signal and a second gate for applying an AGC voltage which varies the gain. The second gate is grounded via a series circuit including a resistor and a DC-cutting capacitor. The impedance of the DC-cutting capacitor is sufficiently lower than the resistance of the resistor in the UHF band.
