AI Technical Summary
In existing technologies, the effective efficiency correction factor of coaxial microwave power references is difficult to determine accurately at high frequencies, and traditional physical isolation methods face bottlenecks in the millimeter-wave band, resulting in insufficient accuracy of coaxial microwave/millimeter-wave power tracing.
By collecting the transient temperature rise potential of the power sensor under RF power and DC power, and using an iterative algorithm to decouple the coupling loss between the heat insulation section and the transmission line inside the seat, combined with the internal transmission line loss calculation, an effective efficiency correction factor calibration without physical isolation is achieved.
It breaks through the bottleneck of traditional physical isolation methods at high frequencies, improves the traceability accuracy of coaxial microwave and millimeter-wave power references, simplifies the calibration process, and expands the frequency application scenarios.
