Измерения мощности электромагнитных колебаний в диапазоне миллиметровых длин волн широко применяются в радиосвязи, радионавигации, радиолокации. С целью обеспечения единства измерений мощности электромагнитных колебаний в диапазоне частот 78,33–118,1 ГГц усовершенствован Государственный первичный эталон единицы мощности электромагнитных колебаний в волноводных трактах в диапазоне частот от 37,5 до 78,33 ГГц ГЭТ 167-2017. Для увеличения верхней частоты ГЭТ 167-2017 разработан комплект болометрических измерительных преобразователей в волноводных трактах 2,4×1,2 и 2,54×1,27 мм (WR10), калориметрическая и компарирующая установки. Приведены структурная схема, технические характеристики и результаты метрологических исследований Государственного первичного эталона единицы мощности электромагнитных колебаний в волноводных трактах в диапазоне частот 37,5–118,1 ГГц ГЭТ 167-2021. С учётом особенностей, вызванных уменьшением сечения волноводного тракта, уточнены методики оценки составляющих погрешностей воспроизведения и передачи единицы мощности электромагнитных колебаний. Результаты исследований подтвердили высокие показатели точности эталона, который теперь занимает лидирующую позицию среди аналогичных национальных эталонов.</p></abstract><trans-abstract xml:lang="en"><p>Radio frequency power is the main parameter characterizing the intensity of electromagnetic radiation at microwave frequencies in closed transmission paths. Measurement of the RF power in the millimeter wavelength range is widely used in radio communications, radio navigation, and radar. In order to ensure the uniformity of measurements of the RF power in the frequency range from 78.33 to 118.1 GHz, the State Primary Standard of the unit of RF power in waveguide paths in the frequency range from 37.5 to 78.33 GHz GET 167-2017has been improved. To ensure the possibility of increasing the upper frequency of the GET 167-2017, the development of sets of bolometric measuring transducers in waveguide paths 2.4×1.2 and 2.54×1.27 mm (WR10), calorimetric and comparating installations. The block diagram, technical characteristics and results of metrological studies of the State primary standard of the unit of RF power in waveguide paths in the frequency range of 37.5–118.1 GHz GET 167-2021 are given. Taking into account the features caused by a decrease in the cross section of the waveguide path, methods for estimating error components are refi ned. reproduction and transmission of a unit of RF power. The research results confi rmed the high accuracy of the standard, which now occupies a leading position among similar national standards.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мощность электромагнитных колебаний</kwd><kwd>первичный эталон</kwd><kwd>микрокалориметр</kwd><kwd>ваттметр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radio frequency power</kwd><kwd>primary standard</kwd><kwd>microcalorimeter</kwd><kwd>power meter</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shimaoka K., Kinoshita M., Fujii K., Tosaka T., Calibration of mmwave power meters using a broadband calorimeter in the frequency range from 110 GHz to 170 GHz, 2013 38th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2013, pp. 1–2. https://doi.org/10.1109/IRMMW-THz.2013.6665712</mixed-citation><mixed-citation xml:lang="en">Shimaoka K., Kinoshita M., Fujii K., Tosaka T., Calibration of mmwave power meters using a broadband calorimeter in the frequency range from 110 GHz to 170 GHz, 2013 38th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2013, pp. 1–2. https://doi.org/10.1109/IRMMW-THz.2013.6665712</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">He Wei, Zhang Weiwei, Qi Wanquan, Yin Hongcheng, Design of a 110 GHz to 170 GHz calorimeter, 2017 International Workshop on Electromagnetics: Applications and Student Innovation Competition, 2017, pp. 71–73. https://doi.org/10.1109/iWEM.2017.7968788</mixed-citation><mixed-citation xml:lang="en">He Wei, Zhang Weiwei, Qi Wanquan, Yin Hongcheng, Design of a 110GHz to 170GHz calorimeter, 2017 International Workshop on Electromagnetics: Applications and Student Innovation Competition, 2017, pp. 71–73. https://doi.org/10.1109/iWEM.2017.7968788</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Kwon J., Hong Y., Kang N., D-Band Waveguide Microcalorimeter for Millimeter-Wave Power Standard, 2018 Conference on Precision Electromagnetic Measurements (CPEM 2018), 2018, pp. 1–2. https://doi.org/10.1109/CPEM.2018.8501192</mixed-citation><mixed-citation xml:lang="en">Kwon J., Hong Y., Kang N., D-Band Waveguide Microcalorimeter for Millimeter-Wave Power Standard, 2018 Conference on Precision Electromagnetic Measurements (CPEM 2018), 2018, pp. 1–2. https://doi.org/10.1109/CPEM.2018.8501192</mixed-citation></citation-alternatives></ref><ref id="cit4"><label>4</label><citation-alternatives><mixed-citation xml:lang="ru">Перепелкин В.
