| Zusammenfassung: | A high frequency amplifier includes a first transistor and a second transistor, a first drain pad connected to the first transistor and a second drain pad connected to the second transistor, a matching circuit pattern having a first transmission line connected to the first drain pad and a second transmission line connected to the second drain pad, a first wire and a second wire, and a wiring pattern connected to the first drain pad via the first transmission line and the first wire and connected to the second drain pad via the second transmission line and the second wire. An effective impedance of the second wire is larger than an effective impedance of the first wire. The matching circuit pattern has an asymmetrical external shape. An electrical length of the second transmission line is shorter than an electrical length of the first transmission line. |
