Dept. of Electrical and Electronic Engineering. DRO Dielectric resonator Series feedback Theses -- Electronic engineering Dissertations -- Electronic engineering Oscillators, Microwave Dielectric resonators Parametrons Electrical and Electronic Engineering Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2007. Clear procedures for designing dielectric resonator oscillators (DROs) are presented in this thesis, including built examples to validate these design procedures. Both series and parallel feedback DROs are discussed and the procedures for building them are presented. Two examples at different frequencies for each type of DRO are constructed and tested with the results shown. The first is at a frequency of approximately 6.22 GHz and the second for the higher frequency of 11.2 GHz. The DROs for the desired frequencies are designed using the Microwave Office (MWO) software by AWR with the design based on the small-signal model (scattering parameters). Oscillators are produced using the negative resistance method. The circuit achieves low noise by using a dielectric resonator with a high Q factor. Both the series and parallel feedback DRO circuits can be mechanically tuned around the resonant frequency to maximize performance. 2008-02-11T07:41:41Z 2010-06-01T08:43:57Z 2008-02-11T07:41:41Z 2010-06-01T08:43:57Z 2007-12 Thesis http://hdl.handle.net/10019.1/2235 en University of Stellenbosch 3005658 bytes application/pdf application/pdf Stellenbosch : University of Stellenbosch |
