Compact RF planar filters-Improvement of the out-of-band rejection and tunabiliity
Tuesday March 18, 2014 at 10:45
Abstract : The purpose of this work was to develop RF bandpass filters in PCB technology, with three main objectives. The first objective was to develop synthesis formulas to simplify the design procedure of the filter. The second was to achieve wide out-of-band rejection without modifying the in-band filtering characteristics. The third objective was to control the center frequency of the filter by using varactor diode. The bandpass filter topology treated in this thesis is based on Stub-Loaded Resonators (SLR).
