State primary standard of units of complex reflection coefficient and complex transmission coefficient in waveguide paths in the frequency range from 2.14 to 178.4 GHz GET 219-2024

Measurement of complex reflection coefficients and complex transmission coefficients of radio engineering devices in waveguide paths is widely used in radar and radio navigation in the development, production, testing and operation of microwave devices and components. These parameters characterize the quality of matching of transmit-receive paths at ultra-high frequencies. Before the introduction of the State primary standard of units of complex reflection coefficient and complex transmission coefficient in waveguide paths in the frequency range from 2.14 to 178.4 GHz GET 219-2024, metrological traceability of units of complex reflection coefficient and complex transmission coefficient in waveguide paths was ensured to the working standards developed in the 1980s. The operating frequency ranges and automation level of outdated standards did not meet modern requirements and did not fully provide a solution to modern measuring tasks. In order to ensure the uniformity of measurements of complex reflection coefficients and complex transmission coefficients, the State primary standard of units of complex reflection coefficient and complex transmission coefficient in waveguide paths in the frequency range from 2.14 to 178.4 GHz has been developed and approved. The standard provides reproduction, storage and transmission of units of complex reflection coefficient and complex transmission coefficient in 16 domestic and 22 foreign waveguide paths. The block diagram, technical and metrological characteristics of the standard are given. The research results confirmed that standard has comparable metrological characteristics with the standards of national metrological institutes of other countries.
