    Advances of an original noise measurement approach to simultaneous noise and small-signal characterization of networks are presented. This approach features the use of natural noise for exciting the device under test (DUT) and a radiometer for measuring the response from which the DUT's scattering and noise parameters are then extracted. Different radiometer systems for measurements of one- and tw... View full abstract»
