Patent abstract
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).
