A técnica de feedback de sinal de segunda harmônica é aplicada a um amplificador de potência HBT para sistema de comunicação móvel CDMA de banda larga (W-CDMA) para melhorar sua linearidade e eficiência. Este artigo descreve o efeito de feedback do sinal de 2º harmônico da saída do amplificador para a entrada nos produtos de distorção de intermodulação de 3ª ordem (IMD) e potência de vazamento de canal adjacente (ACP) do amplificador de potência. O amplificador de realimentação, usando um HBT InGaP/GaAs com 48 dedos de 3
