Abstract
This paper gives a detailed discussion about the gain ripple effect. Using gain equalization to compensate for the gain ripple and improve the working band of the Linearizer-TWTA system is proposed. A Ku-band equalized RF predistortion linearizer for linearizing the distortion effects of travelling wave tube amplifiers (TWTAs) is proposed. Per-tone and two-tone test experimental results show that the equalizer has improved the working band of the predistortion linearizer. A minimum of 4 dB of AM-AM improvement is made within the whole bandwidth of the TWTA, with a 20° phase shift improvement. And the maximum C/IM improvement after equalization is 3.5dB.
