Synthesis and design of novel active MMIC matched filters for ultra-wideband impulse radio

Summary form only given, as follows. In this paper, a novel active matched filter for UWB impulse radio lower band (3–5 GHz) is presented. Based on a tapped delay line structure, the matched filter delays and sums the UWB signal coherently to improve output signal to noise ratio (SNR). A four stage matched filter with a full cycle delay at centre frequency (4 GHz) is proposed. To reduce the amount of phase delay, a novel half cycle delay matched filter is then introduced. SNR improvement is verified through Monte Carlo simulations.
