Abstract

Piezoelektrisk resonator (10) med redusert tendens til parasittsvingninger, stor frekvensforskjell AF mellom resonato- rens parallellresonansfrekvens og dens serieresonansfrekvens, regulerbar kapasitet mellom dens ytre elektroder (20, 22), og stor grad av fleksibilitet ved kon- struksjonen. En eller flere slike reso- natorer kan brukes til å bygge opp en elektronisk komponent (30, 50). Resonatoren har en kjerne (12) som er utformet ved laminering av f.eks. piezoelektriske lag og indre elektroder (14). Kjernens (12) dimensjoner kan være slik at lengden (L) er større eller lik to ganger bredden (W), og samtidig større eller lik to ganger tykkelsen (T) . Kjernen er videre polarisert i begge ender av hver indre elektrode (14) i motsatte retninger. Et spor (15) er lagt inn på den ene av sideflatene på kjernen (12), og begge sider av sporet har sine indre elektroder (14 ) dekket med to isolerende filmer eller lag (16, 18). Disse isolasjonslag dekker avvekslende den ene og den andre indre elektrode (14) i en rekke, slik at de udekkede av disse kan koples til sin respektive ytre elektrode (20, 22).
