Abstract
To be able to perform the S-parameters measurement procedures, the study of using PNA N5225A, calibration kits, gage kit, connectors, probing station, and microscope were necessary. The short-open-load (SOL) and short-open-load-thru (SOLT) calibration methods were used before the measurements to obtain accurate results. The GS/SG 500 Z-Probes were used to obtain single-ended S-parameters and CSR-5 calibration substrate was used to perform SOL and SOLT calibrations. The printed circuit board design with SMA connector was made to measure its mixed-mode S-parameters measurements. The mixed-mode S-parameters can be obtained either from single-ended S-parameters by conversion, or from true mixed-mode S-parameters measurements. The integrate true-mode stimulus application was required for the true mixed-mode S-parameters measurements. The researchers designed three devices under test and calibration kits for SMA connector. These devices under test included (1) no trace, (2) with trace, and (3) with trace and vias devices. These devices represented the simplest possible power distribution networks, and he demonstrated applying mixed-mode S-parameters to these measurements. Since these devices did not include any components, so the measurement results from the conversion and the true measurements came out to be really close. Due to the limitation of the tool used, the measurements has been performance in the frequency range between 10MHz ~ 5GHz.
