Broadband noise generators are used in various radio engineering devices mainly as calibration or reference sources when measuring the noise coefficient, checking the frequency response and transmission coefficients. To obtain reliable measurement results, it is necessary that the noise generated by the source has a uniform spectral density in the required frequency range and high stability of characteristics. The purpose of the work is to establish which types of zener diodes can be used as sources of RF noise, to determine the conditions of their operation allowing to obtain the maximum level of uniform spectral power density of noise radio emission at frequencies up to 1 GHz and higher. An experimental setup was developed and noise measurements of different types of zener diodes were made at different values of the reverse current. The regularities of the occurrence and change of noise in different types of diodes and the optimal modes for this are revealed. The results obtained in the work allow us to choose the type of diode most suitable for the tasks and its operating mode, which makes it possible to use zener diodes as generators of the reference noise signal in microwave radiometers.
