Design and Realization about Transmitter of High Speed Digital Transmissions in Satellite Communications

提出了一种卫星通信中高速数据传输发射机的设计方案,并给出了此方案具体的硬件实现。在硬件上选用一种新型的高速D/A芯片TS86101G2B,在系统设计中充分利用该芯片高线性度、宽动态范围以及高速的特点,实现了卫星通信中数字信号高速率、高质量的稳定传输,为包括卫星通信在内的高速数据传输发射机的设计与实现提供了一个新的参考。

This article introduces a kind of design options about the transmitter of high speed digital transmissions in satellite communications,and gives the main hardware realization of the option. A new kind of high speed D/A chips TS86101G2B is used in the hardware realization. The chip＇s characters of high linearity, wide dynamic range and high speed are fully used in the system design. The digital signals＇ steady transmission of high speed and good quality is realized in satellite communications. A new reference is provided to the design and realization about the transmitter of high speed digital transmissions including satellite communications.
