Abstract

The invention provides a device parameter measurement method and device and terminal equipment. The method comprises the steps of obtaining measured data of a to-be-measured device and an error parameter of a load pull measurement system, wherein the measured data is a voltage wave measured by an internal receiver of a vector network analyzer in the load pull measurement system on the basis of theto-be-measured device; and calculating a parameter of the to-be-measured device by utilizing the measured data and the error parameter of the load pull measurement system. Through obtaining the real-time measured data, measured by the vector network analyzer, of the to-be-measured device, the parameter of the to-be-measured device can be calculated in real time without being influenced by the mechanical repeatability of an impedance tuner, so that the measurement accuracy for the parameter of the to-be-measured device is improved.

Description

technical field [0001] The invention belongs to the technical field of semiconductors, and in particular relates to a device parameter measurement method, system and terminal equipment. Background technique [0002] Due to its measurement model, the current load-pull measurement system needs to use a vector network analyzer to pre-characterize the source and load impedance states at each frequency point during the self-calibration process, and then store them in the software. Then configure the impedance adjuster to the same impedance state, and call out the stored data. At present, the load-pull measurement system is used to measure the device under test. Because the mechanical repeatability of the load-pull measurement system has a great influence on the test accuracy, the measurement of the device to be tested by the load-pull measurement system is inaccurate, resulting in the final calculation of the device under test. The parameters are not accurate. Contents of the ...
