摘要：
Mathematical model of microstrip transmission line with losses used as a final load or a highpower attenuator is developed. The model is based on the decomposition impedance approach. The equivalent circuit, which represents impedance analog of the load, is obtained by partitioning the resistant stratum surface on a two-dimensional grid from elementary blocks. The division of the blocks in the crosssection invoeves current heterogeneity of the microstrip transmission line. The connection between elementary blocks in the cross-section is described by means of crossinductively. It ensures galvanic outcome of resistors which are used to describe dispersion of microwave power, and allows to define precisely an input impedance on zero frequency. Developed model can be used on frequencies from 0 up to 20 GHz for high-power loads having significant longitudinal and transversal sizes.
