Construction of mm-band and cm-band radiometers based on satellite low noise blocks

摘要

Features of construction of mm-band and cm-band radiometers based on satellite low noise blocks (SLNB) are examined. The characteristics of the developed and constructed radiometer layout are presented. The experimental results are shown and compared with the published data. The possibility of using SLNB as an HF intermediate amplifier of mm-band radiometers and two-bandwidth radiometers is examined. A conclusion about receiving apparatus has been made.
