Development of a SOLT Calibration Setup for SAW Sensor Characterization

摘要

In this paper is reported the development and validation of a calibration kit, made of standard loads, specifically dedicated to SAW resonators, with TO39 package. By using this calibration kit it is possible to perform a SOLT (Short Open Load Thru) VNA (Vectorial Network Analyzer) calibration, allowing the deembedding of the package parasitic effects in a frequency range up to 500 MHz. The developed calibration kit was employed in the characterization of a SAW sensor based on Poly (methacrylic acid) (PMA) as sensing material for ethanol monitoring.
