ADSL 接入技术已成为终端用户最主要的宽带接入技术。ADSL 技术的关键是ADSL 调制解调器,即ADSL MODEM。ADSL 用户端调制解调器驱动器是一个宽频带功率放大器,他能不失真放大和传输电话线上已编码的数字信号。 本文通过对ADSL 调制解调器驱动器特点、结构和性能的分析,给出了一种ADSL 用户端MODEM 驱动器的实现电路。该 电路采用具有优良高频的双功率放大器L T1886 ,即使在配置高电平的闭环增益网络后也能保持较低的失真。-ADSL access technology has become the most important end-user broadband access technology. ADSL technology is the key to ADSL modem, that is, ADSLMODEM. ADSL modem client driver is a broadband power amplifier, the distortion that he can not enlarge and transfer telephone lines have been encoded digital signal. Based on the ADSL modem driver characteristics, structure and performance analysis, we give a ADSL client realize MODEM driver circuit. The circuit has an excellent high-frequency power amplifier of the dual-L T1886, even though high in the configuration of the closed-loop gain network also able to maintain low distortion.
