Abstract
An amplifier includes a transistor chip, a matching chip with a capacitor group having multiple MIM capacitors, each of the MIM capacitors including a lower electrode, a dielectric, and an upper electrode, a bonding wire that electrically connects the transistor chip to the upper electrode of any one of the MIM capacitors of the capacitor group and transmits a high-frequency signal, and a case that accommodates the transistor chip and the matching chip. The lower electrodes of the MIM capacitors are grounded, and capacitance values of each of the MIM capacitors of the capacitor group are different from each other.
