| Abstract(in English) | Microwave vector network analyzer (VNAs), easy to calibrate, are most commonly used as an ultra-wideband (UWB) channel sounder to measure the propagation characteristics of UWB signals. The measurement distance is, however, limited by the loss of a coaxial cable connecting a VNA output port and a transmitting antenna. A UWB over fiber transmission system was developed to replace the coaxial cable transmission which has frequency dispersion as well as the large amount of transmission loss. The developed system consists of a wideband laser diode, a single-mode optical fiber cable, and a photo diode. This system showed a transmission loss of around 27 dB, a root-mean-square loss variation of 2 dB, and a group delay of less than 0.7ps. Typically for more than 30-m transmission, this system outperforms coaxial cables in transmission loss and frequency dispersion. An experimental result of UWB propagation was shown to demonstrate the usefulness of this system. |
