We have developed novel microwave attenuation measurement systems using heterodyne receivers at 0.05−26.5 GHz. The leakage, noise floor and DR of the system have been analysed. The receiver noise floor is around −172 dBm, with a record high DR of ~186.7 dB at 26 GHz. A microwave phase-shift measure...
