RF Power Amplifier Control System with Dynamic Load Conditions

Radio frequency (RF) technology plays a crucial role in many fields, and its accurate control and monitoring is of utmost importance. A centralized, multicore processing architecture has been developed to control and monitor high power RF systems with improved accuracy. This system is novel and includes a semi-automated RF power calibration method and a variable VSWR system for dynamic load management with high dynamic range and high resolution (<50dB with. 025dB at 100W) which cannot be provided with the existing methods reported in the literature. The architecture has been integrated with a high-power RF amplifier to provide 1W resolution up to 100W for dynamic loads with VSWRs from 1:1 to 4:1 and variable frequencies from 300KHz to 35MHz.
