| 摘要 |
A radio apparatus (1), in particular for mobile radio, of a first predetermined power stage is proposed, whose broadcasting power can be increased by connecting a HF amplifier circuit. The radio apparatus (1) has an antenna output (5), to which an input (10) of a HF amplifier circuit (15) can be connected, for operating the radio apparatus (1) at a higher, second power stage. As a function of the HF amplifier circuit (15) connected to the radio apparatus (1), a transmitter unit (20) of the radio apparatus (1) outputs signals for transmission to a radio network, which signals contain the information about operation at the applicable power stage.
