Введение. В последнее время большой научный и практический интерес вызывает разработка перестраиваемых радиофотонных СВЧ-фильтров. Такие радиофотонные СВЧ-фильтры являются хорошей альтернативой существующим радиочастотным решениям, так как характеризуются низкими потерями, обладают широким диапазоном рабочих частот и могут быть легко интегрированы в различные телекоммуникационные системы. Использование ацетиленовой газовой ячейки и лазера с перестраиваемой длиной волны излучения позволяет создать перестраиваемый в широком диапазоне частот радиофотонный СВЧ-фильтр.

Introduction

Introduction. Recently, the development of tunable microwave photonic filters has attracted great scientific and practical interest. Such microwave photonic filters are a good alternative to traditional electrical solutions, due to low losses, wide operating frequency range and such filters can be easily integrated into various telecommunication systems. By using an acetylene reference cell and a laser with tunable wavelength can make it possible to create tunable microwave photonic filter with wide operating frequency range.

Aim

Aim. Investigation of the characteristic of a tunable microwave photonic filter based on an acetylene reference cell, as well as research possible solution to reduce losses in filter bandwidth; numerical simulation of microwave photonic filter characteristics.

Materials and methods

Materials and methods. Experimental study was carried out on an experimental prototype of a tunable microwave photonic filter. The filter consisted of a laser with a tunable wavelength, a phase modulator, an acetylene reference cell, an optical fiber connecting the gas cell with a photodetector, and a photodetector. Theoretical study was carried out by modeling of the transmission characteristics of the microwave photonic filter.

Results

Results. Experimental transmission characteristics of a tunable microwave photonic filter were obtained. The tuning of the filter bandwidth by tuning laser wavelength was studied. Modeling of transmission characteristics of microwave photonic filter was performed. Possible solution to reduce losses in filter bandwidth was proposed.

Conclusion

Conclusion. A tunable microwave photonic filter based on an acetylene reference cell is proposed. Losses in the filter bandwidth was about −30 dB. Using high-power laser and a photodetector with a high photocurrent can reduce losses in the filter bandwidth.
