Abstract
This article summarizes the design of a three-frequency feed for the Deep Space Network supporting the 32-GHz downlink, 8.4-GHz downlink, and 7.2-GHz uplink bands simultaneously. Monopulse tracking is also provided at 32 GHz. The design combines high-power uplink operation and ultra-low-noise receive capability in a single feed with no need for frequency-selective surfaces or external diplexers. The key components of the feed will be described along with special considerations taken into account during their design. Experimental results, lessons learned, and ideas for future improvement are also included.
