METHOD FOR DETERMINING PARAMETERS OF SHF DEVICE Russian patent published in 2015 - IPC G01R27/00 

FIELD: electricity.

SUBSTANCE: method for determining parameters of SHF device includes measuring of complex dissipation parameters at n points of the operating, modelling in its operating frequency band of equivalent circuit comprised of active and reactive components, each of them described by the respective parameter unaffected by frequency, determining parameters by mathematical procedure. At that the equivalent circuit of the SHF device is represented as T-shaped connection of three complex resistors Z₁, Z₂, Z₃, at that complex resistor Z₃ is coupled in parallel while complex resistors Z₁ and Z₂ are coupled in series to input and output of the SHF device from the left and right in regard to complex resistor Z₃ respectively, each of three complex resistors is represented by in-series connection of the active element - resistor, which is described by parameter R_i, and two reactive elements - inductance coil, which is described by parameter L_i, and capacitor, which is described by parameter C_i, while determining of the parameters is carried out by mathematical procedure. In the first procedure three complex impedances are defined at n points of the operating frequency band, in the second one - parameters of the SHF device, R_i, L_i and C_i, by the respective mathematical formulas.

EFFECT: simplification of the method and improvement of its determination accuracy.
