    • An RF power amplifier according to the invention comprises a plurality of parallel output transistors (HBT,1,1 to HBT,1,N) connected to a power supply. A plurality of base resistors (Rb,1,1 to Rb,1,N) for the output transistors (HBT,1,1 to HBT,1,N) and a plurality of input capacitors (Cb,1 to Cb,N), each coupled in parallel to receive an RF signal input and connected via at least one additional passive component to the inputs of each corresponding output transistor (HBT,1,1 to HBT,1,N), are provided An output for an RF output signal is obtained from the parallel connection of the output transistors (HBT,1,1 to HBT,1,N). The transistors (HBT,1,1 to HBT,1,N) are heterojunction bipolar transistors.
    • 根据本发明的RF功率放大器包括连接到电源的多个并联输出晶体管(HBT,1,1至HBT,1,N)。 用于输出晶体管(HBT,1,1至HBT,1,N)和多个输入电容器(Cb,1至Cb,N)的多个基本电阻器(Rb,1,1至Rb,1,N) ,每个并联耦合以接收经由至少一个附加无源分量输入并连接到每个对应的输出晶体管(HBT,1,1至HBT,1,N)的输入的RF信号。RF输出的输出 信号从输出晶体管(HBT,1,1至HBT,1,N)的并联连接获得。 晶体管(HBT,1,1至HBT,1,N)是异质结双极晶体管。
