СИНТЕЗАТОР ШИРОКОПОЛОСНЫХ СИГНАЛОВ, СФОРМИРОВАННЫХ МЕТОДОМ ПРЯМОГО ЦИФРОВОГО СИНТЕЗА

Development and experimental studies of the generator of wideband signals were conducted by the method of direct digital synthesis. Generator allows for the correction of phasefrequency characteristics of the formed broadband signal. The level of spurious radiation was investigated at the output of the frequency mixer in the transfer of the signal spectrum in the band of UHF.Проведены разработка и экспериментальные исследования формирователя широкополосных сигналов методом прямого цифрового синтеза. Формирователь позволяет обеспечивать коррекцию фазо-частотных характеристик формируемого широкополосного сигнала. Исследован уровень побочных излучений на выходе смесителя сдвига при переносе спектра сигнала в диапазон СВЧ
