The problem of linearity and broadband matching is the most difficult to solve. When designing QSG in a wide frequency band, there is a problem of forming a quadrature signal using traditional solutions using a polyphase filter or a digital D-trigger. The use of only one method for forming a quadrature signal is impossible due to the limiting features of the electronic component base of SiGe BiCMS technology. To solve this problem, we propose a structure that allows us to develop a broadband quadrature signal generator with an operating frequency range from 10 MHz to 6 GHz, using the method of dividing the operating frequency band. At frequencies from 1 to 6 GHz, the quadrature signal is generated using a polyphase filter, and at frequencies less than 1 GHz using a frequency divider. Using this method, the following characteristics of the FCS have been achieved: the difference in the amplitudes of quadrature signals is less than 0.3 dB; the VSWR is less than 1.6 over the entire frequency range; the transmission coefficient is not less than -2 dB at a 0 dBm heterodyne power; at a frequency of 6 GHz P1dB of at least 3 dBm. The experimental results are in good agreement with the simulation data.</p></abstract><trans-abstract xml:lang="ru"><p>При разработке широкополосного формирователя квадратурных сигналов с использованием SiGe-БиКМОП-технологии наиболее трудно решаются задачи линейности и широкополосного согласования. В широкой полосе частот квадратурный сигнал формируется с помощью полифазного фильтра или цифрового D-триггера. Применение только одного метода формирования является невозможным из-за ограничивающих особенностей электронно-компонентной базы SiGe-БиКМОП-технологии. В работе предложена структура, которая позволяет методом разделения рабочей полосы частот разработать широкополосный формирователь квадратурных сигналов с диапазоном рабочей частоты от 10 МГц до 6 ГГц. На частотах от 1 до 6 ГГц квадратурный сигнал формируется с применением полифазного фильтра, а на частотах менее 1 ГГц - делителя частоты. Использование метода разделения рабочей полосы частот позволило получить следующие характеристики формирователя квадратурных сигналов: разность амплитуд квадратурных сигналов менее 0,3 дБ; коэффициент стоячей волны менее 1,6 во всем диапазоне частот; коэффициент передачи не менее -2 дБ при мощности гетеродина 0 дБм; на частоте 6 ГГц P1дБ не менее 3 дБм. Экспериментальные результаты хорошо согласуются с данными моделирования.</p></trans-abstract><kwd-group xml:lang="ru"><kwd/></kwd-group><funding-group/></article-meta>
