Abstract
An amplifier circuit includes a first FET including first source, first gate and first drain electrodes, and a first field plate having a part thereof provided above a semiconductor layer between the first gate and the first drain electrodes, and a second FET including second source, second gate and second drain electrodes, and a second field plate having a part thereof provided above the semiconductor layer between the second gate and the second drain electrodes, wherein a first distance between an end closer to the first drain electrode in a surface of the first gate electrode and an end closer to the first drain electrode in the first field plate is shorter than a second distance between an end closer to the second drain electrode in a surface of the second gate electrode and an end closer to the second drain electrode in the second field plate.
