|Title:||Vector Corrected Noise Temperature Measurements|
|Published:||June 07, 2002|
|Abstract:||A new one-port noise temperature measurement technique is presented that uses receiver noise parameters for error correction. Improved accuracy in one-port noise temperature measurements made with commercial systems is demonstrated without using isolators. Equations for correcting mismatch errors are developed as part of the available vector noise temperature equation. Results, presented for a C-band solid-state cold noise source and a pair of microwave solid-state noise diodes, are shown to be in good agreement with radiometric measurements of the same sources.|
