Abstract

This work is devoted to modern microwave generators, which compete with electrovacuum microwave generators due to their advantages, such as high power output, design simplicity, and reliability. However, they also have a high noise level, which consists of fluctuation noise, modulation noise, and thermal noise. This paper investigates the physical basis of these noises, including the interaction of carriers with a high-frequency field and nonlinear effects. A diode-type oscillator using a cylindrical resonator and a Tesla VB 0234 diode was experimentally designed and manufactured, and the output spectrum of the oscillator was obtained for different resonator quality factors.
