Abstract

Объектом исследования являются частотно-избирательные устройства приемного тракта беспроводных инфокоммуникационных систем. Целью работы являются синтез и реализация частотно-избирательных устройств приемного тракта беспроводных инфокоммуникационных систем, в том числе: миниатюризированных микрополосковых полосовых фильтров с повышенной селективностью на связанных резонаторах, комплексных фильтров с расширенным динамическим диапазоном. Разработан метод синтеза микрополосковых полосовых фильтров на основе связанных резонаторов, позволяющий реализовать фильтры на основе квазиэллиптической аппроксимации. Разработана методика синтеза комплексных фильтров высокого порядка на основе реактансного преобразования, правильность методики подтверждена результатами моделирования. Реализован транскондуктивный усилитель с низким уровнем нелинейных искажений, на его основе синтезирован фильтр пятого порядка с расширенным динамическим диапазоном. Произведены экспериментальные образцы микрополосковых полосовых фильтров S-диапазона, измерены их S-параметры. Результаты измерений подтверждают корректность разработанной методики.

The object of the study are the frequency-selective devices of the receiving path of wireless infocommunication systems. The aim of the work is the synthesis and implementation of frequency-selective devices of the receiving path of wireless infocommunication systems, including: miniaturized microstrip bandpass filters with enhanced selectivity on coupled resonators, complex filters with an extended dynamic range. A method has been developed for the synthesis of microstrip bandpass filters based on coupled resonators, which makes it possible to realize filters based on quasi-elliptic approximation. A technique for the synthesis of complex filters of high order based on the reactance transformation was developed, the correctness of the technique was confirmed by the results of modeling. A transconducting amplifier with a low level of nonlinear distortion is realized, on its basis a fifth order filter with an extended dynamic range is synthesized. Experimental samples of microstrip bandpass filters of the S-band were made, their S-parameters were measured. The results of measurements confirm the correctness of the developed procedure.
