Sažetak

U ovom radu prikazana je kapacitivna metoda za karakterizaciju LTCC traka u opsegu od 1 do 1000 kHz korišćenjem HP4277A LCZ metra. Objašnjen je princip rada i izvršeno merenje test uzoraka. Prikazana je izrada komponenata u LTCC tehnologiji i uzroci koji mogu dovesti do promene karakterističnih parametara podloge prilikom izrade. Ukazano je na značaj poznavanja zavisnosti permitivnosti od učestanosti pri projektovanju i simulaciji elektronskih komponenti i kola u LTCC tehnologiji. Izvršeno je merenje kompleksne permitivnosti, tangensa ugla gubitaka i Q-faktora na osnovu izvedenih formula za uzorke LTCC traka. Razvijen je poseban korisnički program koji omogućava automatsku kontrolu merenja, proračun željenih veličina i obradu rezultata.
