High Precision and Fast RF Power Measurement using Linear Regression Technique over FPGA

Abhishek Parikh; Sandeep Shah; Vijay Faladu

Fast and precise power measurement of RF frequency in VHF and UHF band is important and can be used in multiple applications like characterization of high-power amplifier (HPA) and solid-state power amplifier (SSPA), fast interlocking system for plasma process control and feedback diagnostics. Good research has been done on measurement and interlocking amplifier systems using analog devices, flip-flops and hardware logic gates, calorimeter and bolometer. There are several limitations like This paper describes a novel technique in which prediction of RF power dBm by measurement of voltage across monolithic RF power detector IC and fast interlocking system. We have got best accuracy of 0.04% and speed of the acquisition is less than 1uSec.
