Evaluation of ultra wideband (UWB) signal transmission, propagation and reception with low cost UWB RF front end

We present ultra wideband signal measurements in an indoor environment using a simple UWB transmitter and receiver at some defined ranges. At the transmitter side, the UWB source is generated using a low cost sub-nanosecond impulse generator, triggered by a rectangular pulse, and transmitted with SkyCross's UWB antenna. At the receiver side, the UWB signal is received by SkyCross's UWB antenna and subsequently amplified by an ultra wideband low noise amplifier (LNA). The frequency spectrum and time domain waveform of the UWB signal, transmitted and received over defined ranges, is presented. The primary study in this paper is to demonstrate short-range low power UWB signal transmission, propagation and reception and its simplicity of implementation.
