摘要：
Joint measurement of stochastic parameters of a low noise amplifier (LNA), based on output power measurement for input termination impedances is considered. As an advantage of this method the noise parameters can be determined in a quick way for narrow and broad band applications without special equipment. Knowing the noise parameters helps the user designing both matching networks fir given low noise amplifiers and fir optimizing amplifiers. Four real parameters characterize the amplifier with the noise figure as function of the matching network. About ten different values for input termination impedances also provide an estimation of sensitivity and accuracy of this new method.
