Abstract :
A predistortion technique capable of improving CTB by 10 dB has been demonstrated. The output power of the broadband RF amplifier can deliver as much as 51 dBmV with 7 dB slope under 78 NTSC channel loading while CTB performance of 64 dB was obtained with the help of a predistortion technique.
