| Résumé : | Test fixtures for evaluating microwave components usually consist of two unmeasurable sections, each having, for example, one coaxial and one microstrip terminal. A method is proposed for evaluating the S-parameters of these sections through three conventional reflection/transmission measurements. The method rests on the use of an auxiliary two-port. No microstrip standard is needed, except for a load that is necessary if the SWR (standing wave ratio) of the auxiliary two-port is not low enough. Only one reflection measurement with a load has to be performed on the auxiliary two-port. This may even by canceled if this two-port is a transition with low SWR. The method is broadband, frequency-insensitive, and extendable to other media. A method is presented based on three reflection/transmission measurements that minimizes the microstrip hardware, only a load is needed or even no standard at all. The method is directly adaptable to other environments such as waveguide and finline. |
