PROBLEM TO BE SOLVED: To reduce the size of an amplifier having two stages of FETs and inter-stage matching circuit on a separate semiconductor substrate. SOLUTION: This amplifier comprises a FET 1 consisting of units U1-U2, an FET 2 composed of units U11-U16 formed such that their gate electrodes are formed in parable on the same semiconductor substrate 11, and drain lead electrodes 23a, 32a of the FETs 1, 2 are arranged on the same side face of the substrate 11, so as to facilitate connecting the FETs 1, 2 to an inter-stage matching circuit and attaining a miniaturization of the amplifier. |
