1results about How to "Reduce error" patented technology

This invention discloses a radio frequency (RF) control method based on tuning response and harmonic optimization, relating to the field of RF technology. The method includes: Step S1: Generating an array configuration word in the target RF system using a multi-capacitor switching array; Step S2: Generating an initial RF signal by driving a switch state switch using the multi-capacitor switching array; Step S3: Iteratively calculating notch filter parameters using an iterative optimization method; Step S4: Configuring the iteratively generated optimal notch parameters to the notch filter to filter and correct the initial RF signal. Compared with existing technologies, this invention utilizes a multi-capacitor switching array to acquire RF signal spectral data, constructs an iterative optimization process, and combines iterative optimization of notch filter parameters with optimal notch parameter correction, thereby reducing the system's residual harmonic measurement value. It has the advantages of effectively reducing residual spurious power and maintaining high signal-to-noise ratio and low error performance, while reducing systemic interference.
