Abstract
Four X-band traveling-wave maser (TWM) systems with effective input noise temperatures of 3.5 K and bandwidths varying from 65 to 108 MHz have been supplied to the Deep Space Network. These TWMs are used on the 64-meter antennas at Deep Space Stations 14, 43 and 63 at 8420 MHz to meet the requirements of the Voyager-Saturn encounter. The TWMs use shortened and cooled signal input waveguide to reduce noise and are equipped with superconducting magnets and solid-state pump sources to provide the required stability performance.
