摘要

射频信号的数字生成是软件无线电的一个关键概念。本文提出了一种包含高速δ - σ调制器的数字发射机链。它还包括基带处理、采样率转换、数字上变频器和输出级(开关模式放大器和BAW滤波器)。在WCDMA标准的δ - σ调制器的7.8 GS/s输出上获得了大约74 dB的ACLR(相邻信道泄漏比)。

All-digital RF signal generation for software defined radio

Digital generation of radio-frequency signals is a key concept of software defined radios. This paper presents a digital transmitter chain including a very high-speed delta-sigma modulator. It comprises also baseband processing, sample rate conversion, digital upconverter and output stages (switching- mode amplifier and BAW filters). About 74 dB of ACLR (adjacent channel leakage ratio) is obtained on the 7.8 GS/s output of the delta-sigma modulator for the WCDMA standard.
