Abstract
Low-pass microwave filters have been built and tested in the laboratory and are now ready for installation in the 14.3- to 16.3-GHz traveling wave maser presently being used on the 64-m antenna at Goldstone Deep Space Communications Complex. These filters, when placed in the input and output lines of the traveling wave maser, will prevent possible calibration errors caused by traveling wave maser gain changes resulting from pump frequency radiation into the signal waveguides. These filters are matched at the signal frequency of the traveling wave maser, have low insertion loss, and will operate at 4.5 K. Therefore, no significant degradation in system performance results.
