A lumped-element equivalent-circuit model is used to represent the device under test at the considered temperature conditions and a parameters extraction process based on a Lorentzian fitting is developed for the determination of the equivalent-circuit elements in the investigated temperature range. A very good agreement is observed between the performed measurements and the model simulations. The characterization process and the subsequent equivalent-circuit parameters extraction at different temperature values are described and discussed.<\/jats:p>","DOI":"10.3390\/s22072546","type":"journal-article","created":{"date-parts":[[2022,3,27]],"date-time":"2022-03-27T21:31:25Z","timestamp":1648416685000},"page":"2546","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Equivalent Circuit Model Extraction for a SAW Resonator: Below and above Room Temperature"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6500-2232","authenticated-orcid":false,"given":"Giovanni","family":"Gugliandolo","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Messina, 98158 Messina, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2954-7275","authenticated-orcid":false,"given":"Zlatica","family":"Marinkovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Electronic Engineering, University of Ni\u0161, 18000 Ni\u0161, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6666-6812","authenticated-orcid":false,"given":"Giovanni","family":"Crupi","sequence":"additional","affiliation":[{"name":"BIOMORF Department, University of Messina, 98125 Messina, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4763-9904","authenticated-orcid":false,"given":"Giuseppe","family":"Campobello","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, 98158 Messina, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1554-2182","authenticated-orcid":false,"given":"Nicola","family":"Donato","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, 98158 Messina, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4","DOI":"10.1112\/plms\/s1-17.1.4","article-title":"On Waves Propagated along the Plane Surface of an Elastic Solid","volume":"S1\u201317","author":"Rayleigh","year":"1885","journal-title":"Proc.
