Abstract

The invention is suitable for the technical field of non-real-time on-chip load traction measurement, and provides a method for obtaining a power calibration model and terminal equipment. The method comprises the steps: obtaining an S parameter and a reflection coefficient of each assembly in an on-chip load traction system; based on different source powers of a signal source in the on-chip load traction system, calibrating the output power of a straight-through piece connected into the on-chip load traction system, and obtaining the output power of each power measurement end surface of the straight-through piece and the input power of the straight-through piece according to the S parameter and the reflection coefficient; constructing a power calibration model according to the output powerof each power measurement end surface of the straight-through piece and the input power of the straight-through piece; and using the power calibration model for power measurement, so that the outputpower can be calibrated before the output power is measured in a non-linear state. The system measurement index and performance during power device measurement can be improved, and the complexity of the measurement process is reduced.

Description

technical field [0001] The invention belongs to the technical field of non-real-time on-chip load pulling measurement, and in particular relates to a method for acquiring a power calibration model and a terminal device. Background technique [0002] When the on-chip load-pull measurement system performs output power measurement, it needs to perform self-calibration according to the prompt of the system measurement software. The self-calibration includes source power calibration measurement and S parameter calibration measurement. After the self-calibration is completed, the S parameter stored in the on-chip load-pull measurement system software is used for measurement, that is, the output power measured by the microwave power meter in the on-chip load-pull measurement system is calculated from the end face 4 to the output probe end face 2 of the DUT , so as to realize the output power measurement of the DUT under different load reflection coefficients. However, the existing...
