In this paper, we present a general way of designing a high Q-factor Bragg resonator, using a simple model of non-Maxwellian equations. The method is a more general method, which allows us to design resonators of cylindrical geometry and arbitrary thicknesses for either the horizontal or cylindrical dielectric reflectors, which is often imposed by the manufacturer. In this work, we only consider cylindrical symmetric resonators operating in transverse electric mode (TE0,n,p), which only has the E 0 component made from low-loss single crystal dielectrics. The horizontal plates are of thickness 2.75 mm and radius 24.3 mm, and the rings are 31.8 mm high and of the same radius. The size of the cavity to obtain Bragg reflection may be calculated using the simple model, which is verified with rigorous method of lines analysis. When we fix the number of variation of E0 in r and z directions to the minimum (fundamental mode) we obtained an unloaded Q-factor of order 2times105 at 9.7 GHz in a single crystal sapphire resonator. Two other cavities were built to investigate Bragg confinement of higher order modes in the sapphire structure at 12.4 GHz with unloaded Q-factors of order 105. We also illustrate the general designing principles of a Bragg reflector with dielectric layers of arbitrary thicknesses using the simple model, with verification using the method of lines","PeriodicalId":445945,"journal":{"name":"2006 IEEE International Frequency Control Symposium and Exposition","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130366249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing TCXO solutions can achieve -150 dBc/Hz phase noise floor at the carrier frequency of 100 MHz. The goal of this work was to create a 500 MHz TCXO with Stratum-3 stability performance (0.28 ppm over temperature, 4.6 ppm over all conditions), which can reach -155 dBc/Hz noise floor, -120 dBc/Hz at 1 KHz offset from the carrier, while providing +7 dBm of output power. The goal was accomplished by integrating in a small SMD package high performance, low frequency, Stratum-3 digitally compensated reference TCXO, low noise off-the-shelf phase locked loop (PLL) IC, and ultra low noise 500 MHz VCXO. The key solutions for this development besides solid digitally compensated TCXO design were optimization of the PLL circuit, and design of a VCXO. The VCXO is based on a 3rd overtone 100 MHz AT-cut crystal resonator with relatively high Q, passive band-pass filter, tuned on the fifth harmonic of the 100 MHz VCXO, and a free-running L-C oscillator, which is injection locked to the above mentioned fifth harmonic of the VCXO. The resulting device performance met all the stated goals and even somewhat exceeded the phase noise expectations. The sub-harmonic suppression was better than 50 dBc","PeriodicalId":445945,"journal":{"name":"2006 IEEE International Frequency Control Symposium and Exposition","volume":"19 2-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134179009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
