Abstract :
Balance-unbalance conversion factors and radiated emissions from differential type microstrip lines (DML) have not been examined in the frequency range above 1 GHz, because it is difficult to obtain the balun that can be used in GHz band. In this paper, we tried to measure them in the frequency range above 1 GHz by using mode analysis function of a network analyzer instead of balun, and compare with the calculation values by using the 4-terminal pair networks chain matrix theory. As their results, it was confirmed that this calculation method is effective in the frequency range above 1 GHz.
