“…In one such recent example (Zheng et al, 2010), UWB noise was generated based on the chaotic dynamics of a laser diode within a fiber-optic feedback loop. UWB noise can be readily generated using electrical techniques (Upadhyaya, 1999), however optical methods are nonetheless appealing as part of a radio-over-fiber integrated system. The rejection of interfering signals in UWB receivers relies on a proper matched filtering of incoming waveforms.…”

One type of favorite source signals is a white noise signal having a Gaussian PDF 1 . Such a signal has a relatively flat signal spectrum density. White Gaussian noise generators can serve as useful test tools in solving engineering problems. Test and calibration of communication and electronics systems, cryptography and RADAR jamming are examples of noise generator applications. In this paper design and implementation of an X-band noise generator used in identifying the specification of the communication and electronics systems is described. This noise generator has 3dB bandwidth of 4GHz (7-11GHz), 60dB of ENR 2 and -114dBm/HZ of noise density.
