Get 107-2019 Special State Primary Standard of the Unit of Electrical Capacitance in the Frequency Range from 1 to 300 MHz

This paper presents the composition and characteristics of GET 107-2019 Special State Primary Standard of the unit of electrical capacitance in the frequency range of 1–300 MHz. The upper limit of the frequency range for reproducing electric capacitance was expanded to 300 MHz due to the development of a new reference installation with an operating frequency of 300 MHz. The operational principles of the installation and algorithms for processing measurement results are considered. The residual relative systematic error of GET107-2019 ranges from 5·10–5 to 1·10–3 (depending on the operating frequency). The relative standard deviation of the measurement result when reproducing the unit ranges from 3·10–6 to 3·10–4, which exceeds the capabilities of national standards in other countries. An updated State Verification Scheme for measuring electrical capacitance in the frequency range of 1–300 MHz was developed and approved. GET 107-2019, along with its subordinate standards and measuring instruments, is widely used in microand nanoelectronics, biomedicine, radioelectronic industry, instrument engineering, as well as in the development and production of modern materials and equipment.
