Abstract :
A white noise generator for VHF/UHF bands has been designed and implemented. The designed circuit employs the avalanche characteristics of a diode combined with wideband amplification. This noise generator has a relatively flat -30 dBm output power from 60 MHz to 1200 MHz. The comparison shows good agreement between results of the simulation and that of measurement. This noise generator can be used to test the noise temperature and noise figure of electronic devices and circuits.
