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 6^th -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.
