| 发明名称 | High-frequency power amplifier with doherty extension | ||
| 摘要 | A high-frequency power amplifier comprises a broadband amplifier (30), a Doherty extension (31) and a coupling device (33). In this context, the broadband amplifier (30) provides a power splitter (34), a main amplifier path (64) and an auxiliary amplifier path (65). The Doherty extension (32) provides a first offset line (60), a second offset line (61) and an impedance inverter (62). The broadband amplifier (30) amplifies an input signal and supplies the amplified signal to the Doherty extension (31) or to the coupling device (33). | ||

| 主权项 | 1. A high-frequency power amplifier comprising: a broadband amplifier connected to a Doherty extension and a coupling device via a switching device, wherein the broadband amplifier provides a power splitter, a main amplifier path and an auxiliary amplifier path, wherein the Doherty extension provides at least one first offset line, a second offset line and an impedance inverter, wherein the broadband amplifier amplifies an input signal and supplies the amplified signal to the Doherty extension or to the coupling device, and wherein the switching device is configured to switch the broadband amplifier between the Doherty extension and the coupling device. | ||
