- ItemDie ontwikkeling van 'n koaksiale resoneerderfilter vir implementering in L-band dipleksers(Stellenbosch : Stellenbosch University, 1999-10) Theron, J. D.; Meyer, P.; Stellenbosch University. Faculty of Engineering. Dept. of Electrical & Electronic Engineering.ENGLISH ABSTRACT: The development of a low loss coaxial resonator and the integration of it into a coupled - resonator filter is discussed in the thesis. The filter is of a bandpass type and is used in an L-band diplexer. The filter has a 2% bandwidth at a center frequency of 1.542 GHz. The resonator is developed from fundamental principles and practical considerations to a capacitively-coupled transmission line structure. Various coaxial topologies are investigated in the process and compared. An accurate network and transmissionline model is postulated and compared with practical measurements. Finally an inductively - coupled resonator filter is developed utilising the realised coaxial resonator.
