摘　　要：本文从预失真补偿的基本思路出发 ,分析了外调制光纤 AM- CATV发射机中复合三阶差拍失真 (CTB)补偿网络的基本功能单元及其特性要求 ,提出采用“互补”型二极管阵列产生补偿信号 ,实现宽频带内In this paper,detail theoretical analysis is presented based on the basic function and characteristic of composite triple beat distortion (CTB) compensation circuit in optical fiber AM- CATV externally modulated transmitter,the complementary diode array structure is proposed based on the predistortion linearization,and the CTB compensation in wide bandwidth has been achieved.
