Abstract
We demonstrated the possibility of "real time" noise measurements at microwave frequencies with spectral resolution ~ 8 dB below the standard thermal noise limit. This was achieved by combining the principles of microwave circuit interferometry with signal recycling and minimizing the influence of various technical noise sources on the measurement processes.
