ANALYSIS METHODS MODULATION OF HF-OSCILLATIONS IN KEY GENERATORS
Abstract
Methods for modulating the RF oscillation in key generators and power amplifiers are discussed. Options for obtaining a modulated RF radio on low power level and then increased, and the formation of modulated signal in the power output stage is key generator are analyzed. The scheme managed key generator based on the resonance current of the inverter, providing high efficiency and linear modulation characteristics are shown.
