Abstract (in Japanese) (See Japanese page) 
(in English) A method of estimating the S-parameters of the 4-port circuit is presented. And conditions of loads for 4-port S-parameter estimation by two or one-port measurements are described. In our method, two or three-port of 4-port circuit are terminated with known loads. And the S-parameters between remaining two or one-port are measured. Advantages of our method is that the S-parameters are to be estimated only by solving the system linear equations and the second order algebraic equations. Our method can be applied to determine the S-parameters of the circuit with a difficult port to connect the probe of the instrument as the IC package and to determine the S-parameters of the circuit ground is not common.
