Abstract A method for evaluating the Performance of the on-wafer load-pull measurement system by measuring the measurement error ΔGT 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 (Pout), conversion gain (GT) 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 ΔGT is carried out, and gives the calibration result ΔGT 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 ΔGT (slope 45°); PAE error increases linearly with ΔGT. When PAE is 70% and ΔGT is 0.5dB, the corresponding power added efficiency PAE uncertainty is about 8.5%. After experimental verification, the deviation between the curve of Pout and PAE of measurement result is less than 1%.
