На основе результатов измерений двухчастотных характеристик смесителей, их односигнальных амплитудных характеристик, а также двухсигнальных амплитудных характеристик и динамического диапазона по интермодуляции 3-, 5-, 7и 9-го порядков в гармонической зоне полезного сигнала синтезированы полиномиальные модели высоких порядков, описывающие передаточные характеристики исследуемых смесителей и предназначенные для анализа влияния радиочастотных электромагнитных помех на радиотракты методом дискретного нелинейного моделирования при большом динамическом диапазоне входных воздействий. Полученные модели обеспечивают высокую адекватность и вычислительную эффективность количественного анализа нелинейных процессов и радиопомех, возникающих в приемном оборудовании радиосетей 4G/5G/6G в сложной электромагнитной обстановке.</p></abstract><trans-abstract xml:lang="en"><p>By using the technology of double-frequency testing, an experimental analysis of nonlinear properties of low-power radio-frequency mixers is performed at frequencies of the n7 band allocated in Belarus for 4G mobile communication systems and the n78 band that is planned to be used in Belarus for 5G mobile communications. Based on the results of the measurements of mixer characteristics (the double-frequency characteristics, single-tone amplitude characteristics, as well as two-tone amplitude characteristics and dynamic ranges for 3rd-, 5th-, 7th-, and 9th-order intermodulation) in the harmonic zone of the useful signal, high-order polynomial models describing the transfer characteristics of the considered mixers are synthesized. These models are intended to analyze the effect of radio-frequency electromagnetic interference on radio links behavior in case of a large dynamic range of input signals by using the discrete nonlinear modeling technique. The obtained models provide high adequacy and computational efficiency of quantitative analysis of nonlinear processes and radio interference occurring in receivers of 4G/5G/6G radio networks in a complex electromagnetic environment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мобильная связь 4G/5G</kwd><kwd>FR1</kwd><kwd>электромагнитная обстановка</kwd><kwd>смеситель</kwd><kwd>нелинейность</kwd><kwd>интермодуляция</kwd><kwd>блокирование</kwd><kwd>динамический диапазон</kwd><kwd>полиномиальная модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mobile communications 4G/5G</kwd><kwd>FR1</kwd><kwd>electromagnetic environment</kwd><kwd>mixer</kwd><kwd>nonlinearity</kwd><kwd>intermodulation</kwd><kwd>blocking</kwd><kwd>dynamic range</kwd><kwd>polynomial model</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">Mordachev V.
