Abstract
Methods of combining output power from multiple 20-kW transmitters were examined as an alternative to developing a new 80-kW transmitter for the Deep Space Network (DSN) based on a single klystron. A promising technique using two hybrids and a waveguide phase shifter was developed and successfully tested at a power level of 300 W as a proof of concept. Implementation strategies including interface to the microwave subsystem’s feed, cooling, physical arrangement of components in a beam-waveguide (BWG) antenna, and transmitter reliability were examined. The study concluded that by using five 20-kW transmitters, a capability to provide power levels from 1 to 80 kW could be developed for roughly the same cost as a single-tube 80-kW transmitter and that the multitransmitter approach would be much more reliable and probably less expensive.
