摘要

匹配滤波器是接收机超宽带前端的重要组成部分。提出了一种基于pHEMT技术的3- 5ghz UWB接收机六阶高斯导数脉冲模拟匹配滤波器。仿真结果证实了滤波器的功能匹配，实现了11 dB的幅值增益，信噪比提高了7.4 dB。匹配滤波器的功耗为62 mW，电源为3v。

A Novel 3-5GHz Distributed Amplifier Structure Based Matched Filter for UWB Receiver

Matched filter is an important component in the Ultra wideband front-end of receiver. This paper proposed an analogue matched filter for 6th -order Gaussian derivative pulse in 3-5 GHz UWB receiver by using pHEMT technology. Simulation results confirm the matched filter function and achieve 11 dB in amplitude gain with 7.4 dB signal-to-noise ratio improvement. The power consumption of the matched filter is 62 mW with a 3-V power supply.
