Design and Simulation of LNA for UWB with Broadband Matching Based on Weak Signal
Pages: 68-72
Year: Issue:  1
Journal: Journal of Southwest University of Science and Technology

Keyword:  微弱信号超宽带低噪声放大器宽带匹配;
Abstract: 设计了应用于超宽带系统的低噪声放大器,通过优化噪声电阻,降低了匹配的难度,并最终设计了一个高通滤波器作为输入端的匹配网络,实现了在超宽频带内的匹配,并在噪声性能仅恶化0.4 dB下,获得了最大功率传输,实现了噪声和功率的同时匹配,降低了UWB系统对器件本身的依赖.
