Calculation of a High Frequency Rectangular Film Resistor Inductance

On the basis of decomposition and current strips methods the matrix method of calculation inductive and inter-inductive parameters of the equivalent circuit of high-power microwaves film resistors is submitted. To growth of frequency there is a redistribution of a current in cross section of the film resistor. As thus magnetic interaction between separate sites of cross section changes equivalent inductance of a resistive film also changes. In this work the algorithm of calculation of the equivalent inductance taking into account non-uniform distribution of currents is given. It is shown that at thickness of a film much less than skin layer and preservation of parameters of blocks on which the cross section is broken, equivalent inductance decreases on 5% in comparison with inductance on zero frequency.
