We present microwave loss characterization results for Si and Sapphire - two substrate materials widely used in fabrication of superconducting QC devices. We also demonstrate the experimental testbed that allows us to characterize various dielectric materials in sub-1K temperatures and wide frequency range from 5 - 8GHz. Our measurements of the loss tangent as a function of frequency, temperature and probing power help to identify the dominant loss mechanisms and select optimal materials and fabrication procedures for the next generation of QC devices.
