Экспериментально и теоретически исследован генератор на основе активного кольца, содержащего спин-волновую линию задержки. Экспериментально полученные значения уровня фазового шума, измеренные на частоте 5390 МГц, составили около 105 дБн/Гц при отстройке 10 кГц. Продемонстрирован способ управления уровнем фазовых шумов генерируемого сигнала за счет подбора расстояния между возбуждающими и приемными элементами спин-волновой линии задержки.

A phase noise of microwave oscillators having an active ring circuitry with a spin-wave delay line is theoretically and experimentally investigated. The delay line was made with yttrium iron garnet (YIG) film epitaxially grown on gadolinium gallium garnet substrate. Obtained results demonstrate a management of the oscillator phase noise with a variation of the distance between antennas used for excitation and reception of spin waves in the YIG film.
