Refurbished X band Cryogenic LNAs for radio astronomy, VLBI or Satellite Ground Stations

ESA has recently completed the replacement of all X-band cryo LNAs in its Deep Space Antennas with upgraded models. The original cryo LNAs which were all built and delivered by Callisto in the period 2000 to 2009 are being offered for refurbishment and re-sale. The refurbishment activity will be undertaken by Callisto and will include the replacement of the cryogenic components (cold head, compressor and gas lines), renewal of all vacuum seals and completed RF retest. The systems will be supplied with LNA power supplies, data logging unit and monitoring software. The RF circuits include bandpass filters which could be removed for customers requiring extended RF bandwidth e.g. for radio-astronomy or VLBI. Outline technical details of the equipment are provided in the attached data sheet.
