| Zusammenfassung: | A feed forward RF power amplifier which provides both high efficiency and minimal distortion in broad bandwidth RF applications. The feed forward powe r amplifier includes a main amplifier (16) biased to provide high efficiency a nd an error amplifier (34) biased to provide highly linear operation through substantially the entire operating range. Signal peaks which introduce distortion components at the main amplifier output are cancelled by the line ar operation of the error amplifier (34). |
