摘要：

This paper is intended to detail the practical implementation of a receiver front end, used in an impulse radio ultra-wideband testbed for low data rate communications and ranging. The receiver architecture consists of a filter bank followed by a downconversion stage that relaxes the analog-to-digital converters requirements in terms of input analog bandwidth. The filter bank is implemented by a four-way Wilkinson power divider and by a set of four Gaussian filters. A low noise amplifier stage precedes the filter bank limiting the receiver noise figure and providing the required gain for medium range communications.
