HIGH POWER BROADBAND PULSED MICROWAVE SOLID-STATE POWER AMPLIfIER WITH HIGH AMPLITUDE-PHASE STABILITY

In this paper the principles of measuring the amplitude-phase stability are described. Fa ctors that negatively affect the amplitude-phase stability of a solid-state power amplifier are considered. The results of theoretical calculations and mathematical modeling of the dependence of this stability on various factors are presented, and on the basis of these results the main factors that negatively affect the amplitude-phase stability are identified. In the conclusion I present the results of practical measurements of the stability, and suggest methods to improve the amplitude-phase stability of high-power solid-state power amplifiers.
