✦ Synopsis
The low losses of electromagnetically coupled dielectric resonators render the measured scattering parameters very sensitive to background "noise" contributed by the coupling mechanism, package modes, radiation, and so forth. It becomes important to properly calibrate out this parasitic influence in order to accurately measure the unloaded Q. We report a robust software calibration procedure based on a state-space spectral estimation method, which filters out the background noise and facilitates linear extraction of the unloaded Q.
