| 摘 要： | 幅度与相位相结合的多进制正交幅度调制（MQAM）技术利用载波幅度和相位传递信息比特，具有充分利用带宽、抗噪声能力强等优点，广泛应用于电视、微波通信、光传输等系统。MQAM发送器是研究MQAM调制解调技术的基础。ADL5385是一款硅半导体单片正交调制器件，其频率范围为50—2200MHz。探讨了利用ADL5385设计的155Mb／s（STM-1）128样点QAM发送器，为研究MQAM提供借鉴。

| Abstract: | MQAM technology transmits information bits by means of amplitude and phase of carrier at the same time,which has many advantages as using bandwidth fully and having more anti-noisy characteristics.MQAM has been used in the sys-tems of TV,microwave communication and light transmission.To design MQAM transmitter is the base of studying modula-tion and demodulation technology of MQAM.ADL5385 is a silicon quadrature modulator for use from 50MHz to 2200MHz produced by analog devices,Inc.The paper discusses the d... |
