More Information
Summary:There is provided a low noise amplifier including: an amplifier circuit to which a radio frequency (RF) signal is input and which outputs an amplified RF signal; and the inductance adjusting circuit is connected between the amplifier circuit and a grounding node and is configured to adjust the output inductance of the amplifier circuit by adjusting the inductance in the inductance adjusting circuit, so that the gain change of the amplifier circuit has the same step length. 本发明提供了一种低噪声放大器，所述低噪声放大器包括：放大器电路，被输入射频RF信号并且输出经放大的RF信号；以及电感调整电路，其被连接到所述放大器电路和接地节点之间，并且被配置为通过调整其中的电感来调整放大器电路的输出电感，从而使放大器电路的增益变化具有相同步长。
