光纤AM-CATV外调制发射机中CTB补偿技术
CTB compensation in optical fiber AM- CATV externally modulated transmitter
【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 CTB的补偿
【Abstract】 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.
