Cooling the LNAs on the earth station? Yes. I doubt the LNA on Voyager is actively cooled. I wonder if any feed components (prior to LNA) on the earth station are cooled? [1] does not indicate. Read a paper recently on converting an old NASA earth station with beam waveguide over to a wideband feed. They had to put a rigid waveguide horn on place of the waveguide and actively cool it. |
