| Popis: | The thru-reflect-match (TRM) calibration technique uses as calibration structures a thru, a pair of highly reflecting loads and two loads of impedance close to the measuring system impedance (Z0). In practice, the loads used as match standard may be nonsymmetrical and of impedance different from Z0. By using the ABCD-parameters matrix formalism, in this paper the calibration of a load-pull system is carried out by using a generalized theory of the TRM technique, allowing the use of nonsymmetrical loads of arbitrary impedance. The impact of ignoring the asymmetry and frequency-dependent impedance of the loads used as match standard on the determination of the load-pull contours of constant output power is investigated. |
