Metode za poboljšanje RF performansi mikro-induktorskih i transformatorskih struktura

Abstract

Tematika disertacije obuhvata projektovanje, izradu i karakterizaciju pasivnih induktivnih RF komponenti u PCB i LTCC tehnologiji, kao i poboljšanje njihovih performansi. Izvršena je i karakterizacijarazličitih tipova dielektričnih i feritnih LTCC materijala koji su korišćeni za izradu komponenti. Ukupno je projektovano i izrađeno 37 struktura, 14 induktora i 23 transformatora. Na poboljšanje karakteristika projektovanih struktura, koje se ogleda prvenstveno u povećanju induktivnosti zavojaka, uticalo se izradom projektovanih struktura na supstratima izrađenih od različitih materijala, supstratima formiranih od kombinacije materijala različitih karakteristika, redizajnom osnovnih (polaznih) geometrija struktura i optimizcijom parametara LTCC postupka izrade.

Topic of this theases focuses on design, fabrication and characterization of industive passive RF components in PCB and LTCC technology, as well as on improvement of their performances. Characterization of different types ofdielectric and ferrite LTCC materials that were implemented for component fabrication was also performed. In total, 37 structures were designed and fabricated, of those 14 are inductor structures and 23 are transformers. Performance improvement of designed structures that is manifested through increase of inductance value of structures windings implied fabrication of designed components on substrates formed from different materials, or from combination of two or more materials with different properties, redesign of original design and optimization of LTCC fabrication process parameters.
