Abstract A method for evaluating the Performance of the on-wafer load-pull measurement system by measuring the measurement error ΔG_T of the transducer gain of the passive mismatch attenuation network is introduced. The load-pull measurement system mainly measures the Performance of the power device under test from three aspects: output power (P_out), conversion gain (G_T) and power added efficiency (PAE). By inserting a calibrated precision polarization step attenuator into the load end of the back-end module, the attenuation substitution measurement of ΔG_T is carried out, and gives the calibration result ΔG_T and the curve family of pout and PAE variation, which is convenient for designers to quickly obtain the system measurement Performance. Among them, the P;out error varies linearly with ΔG_T (slope 45°); PAE error increases linearly with ΔG_T. When PAE is 70% and ΔG_T is 0.5dB, the corresponding power added efficiency PAE uncertainty is about 8.5%. After experimental verification, the deviation between the curve of P_out and PAE of measurement result is less than 1%.
