In order to verify the reliability of the circuit???the microwave performance for InP HBTs is analyzedbased on Monte-Carlo method.The larger the fluctuation range is???the higher the accuracy of extracting intrinsicparameters is required.The allowable accuracy range can be inferred from the output performance.The micro???wave characteristics are composed of modeled S-parameters???current gain cut-off frequency and maximum oscilla???tion frequency.The standard deviation of Monte-Carlo numerical analysis can be derived from the uncertaintycurve of the intrinsic parameters of the pi-topology small signal model.The results of Monte-Carlo analysis showthat the requirements for the accuracy of measurement parameters are quite different under different frequenciesand bias conditions???which verifies the reliability of the circuit under different conditions
