Abstract

In the paper, different architectures of fiber-optic distribution systems of microwave signals for active phased array antennas are studied. The fiber-optic system with all-optical gain for microwave local oscillator signals distribution is presented. The fragment of proposed system is realized and characterized. It is experimentally shown that the developed distribution system provides noise-to-signal ratio of - 150 dBc/Hz, output channel power about 1 mW and phase fluctuation between channels less than 1°.

Волоконно-оптическая система распределения сигнала СВЧ-гетеродина для активных фазированных антенных решеток

В статье исследуются различные архитектуры волоконно-оптических систем распределения СВЧ-сигналов для активных фазированных антенных решеток. Представлена волоконно-оптическая система с полностью оптическим усилением для распределения сигналов СВЧ-гетеродина. Реализован и исследован фрагмент предлагаемой системы. Экспериментально показано, что разработанная система распределения обеспечивает отношение шум-сигнал -150 дБн/Гц, выходную мощность канала около 1 мВт и дрейф фазы между каналами менее 1°.
