Development of a radio front end for a UWB ranging embedded test bed

In this paper, we present a modular test bed for ultra wideband ranging. The test bed comprises a 6.5 GHz radio front end interfacing with a baseband pulse transceiver and round-trip-time measurement module and with a flexible digital control and processing platform. The proposed radio front end allows to reduce antenna size and interference from narrowband users, with respect to the baseband pulse transceiver. We provide experimental characterization results, therefore proving the concept for the proposed front end architecture in the context of the considered UWB test bed.
