HIGH-FREQUENCY AMPLIFIER CIRCUIT HAVING A DIRECTLY-CONNECTED BIAS CIRCUIT |
摘要 |
A high-frequency amplifier circuit includes an amplifying transistor and a bias circuit directly connected to said amplifying transistor. The bias circuit includes a bias transistor having a control terminal and an inductor coupled to the control terminal, and the bias transistor also has an output terminal directly connected to the amplifying transistor. A resistor is connected in series with the inductor, and the series-connected components are connected in the circuit between the control terminal and a power supply terminal. By providing an inductor in the amplifier in this manner, loading effects on the amplifying transistor at high frequencies is substantially reduced. |
