PROBLEM TO BE SOLVED: To provide an amplifier circuit providing an improved gain.SOLUTION: The amplifier circuit having plural amplifier elements which are cascade-connected to each other includes: a distribution control section that distributes an input signal, outputs a first distribution signal from a first output terminal, and outputs a second distribution signal of an amplitude different from the amplitude of the first distribution signal from a second output terminal; a first amplifier element with a second terminal grounded, which inputs the first distribution signal to a first terminal, and outputs a first amplified signal which is the amplified first distribution signal from a third terminal; and a second amplifier element that inputs the second distribution signal to a first terminal as a bias input, inputs the first amplified signal to a second terminal, and outputs a second amplified signal of the amplified first amplified signal from a third terminal. The phase of the first distribution signal has the same phase as the phase of the second distribution signal. |
