摘要

本文研究了一种工作频率在1 ~ 6ghz、瞬时带宽为500mhz的超宽带无线电接收机的设计方案。单频率转换(0-IF)架构基于模拟I/Q解调器(ADL5380)和双通道14位模数转换器(AD9680)。对接收机进行了初步测量，并在文中进行了介绍。主要结果包括:噪声系数NF < 7.5 dB，动态范围超过62 dB(通过前端和基带调平电路增强)，高线性度:IIP3 > 21 dBm。

An ultrawideband 1 to 6 GHz 0-IF radio receiver with 500 MHz of instantaneous bandwidth

This paper is related to the project of an ultrawideband radio receiver operating between 1 and 6 GHz with instantaneous bandwidth of 500 MHz. A single frequency conversion (0-IF) architecture is based on analog I/Q demodulator (ADL5380) and two channel 14-bit analog-to-digital converter (AD9680). Preliminary measurements of the receiver have been performed and presented in the paper. Key results include: noise figure NF < 7.5 dB, dynamic range over 62 dB (enhanced by frontend and baseband leveling circuitry), high linearity: IIP3 > 21 dBm.
