Abstract A novel load pull measurement technique based vector error correction method is developed. The technique includes the 8-term vector error calibration on the vector network analyzer and one-tier absolute power calibration for one receiver within the vector network analyzer, which could obtain the input/load reflection coefficient, input/output power and power gain for the device under test at one time. Then the measurement system is set up based the proposed method. Compared with the commercial Focus load pull system, the test result shows they have promising results, which demonstrates the accuracy of the proposed method.
