Thermal and Electrical Characterization of the High Gain Warm IF Amplifier for the GUSTO Radio Astronomy Instrument

The work presented herein will present the methodology and results for characterizing the thermal and electrical characteristics of the high gain warm IF amplifiers being developed by Arizona State University (ASU) for the GUSTO radio astronomy instrument. Thermal analysis will be performed in the form of Thermal Desktop simulations, hand calculations, and lab measurements. The electrical characteristics of the LNA design are then examined by collecting S-parameter measurements of the entire GUSTO band across a temperature range of -40°C to +70°C. Ultimately, the work performed justifies that ASU’s design of the GUSTO electronics is capable of meeting all technical requirements necessary to achieve mission success.
