Abstract
A high-frequency amplifier circuit has a source-grounded first transistor that amplifies a high-frequency input signal, a gate-grounded second transistor that further amplifies the amplified signal, a first inductor and a first reference voltage node, a second inductor connected between a first node and a second reference voltage node, a third transistor that is connected between the first node and a drain of the second transistor, is turned on at the time of selecting the first mode to transmit the amplified signal to the first node, and is turned off when selecting a second mode to disconnect the first node from the drain of the second transistor, a bypass path that bypasses the high-frequency input signal from an input node of the high-frequency input signal to the first node at the time of selecting the second mode, and a bypass switching circuit that is connected on the bypass path.
