Abstract :
This paper presents RF prototype system for DS-CDMA ultra wide-band (UWB) communication. The Federal Communication (FCC) authorized the commercial use of the UWB technology in February 2002. Where, the frequency range of the spectrum mask in an indoor environment is from 3.1 GHz to 10.6 GHz. But because of 5 GHz wireless LAN, they usually use frequency band from 3.1-4.9 GHz. This prototype RF system can be satisfied with these limitations. Its structure is direct conversion and receiver dynamic range is 40 dB (-40 dB -80 dB)
