Design and implementation of an X-band white Gaussian noise generator

One type of favorite source signals is a white noise signal having a Gaussian PDF. 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 3 dB bandwidth of 4 GHz (7-11 GHz), 60 dB of ENR and -114 dBm/HZ of noise density.
