Abstract

Results from a preliminary study of frequency-selective surface (FSS) options for injecting a 100-kW uplink signal into the existing 34-m beam-waveguide systems are described. The FSS approach is viewed as a backup to the preferred approach, which modifies the existing three-frequency (7.2-/8.4-/32-GHz) feed, increasing its 7.2-GHz uplink capability from 20 kW to 100 kW. Several options are considered, including a triplexing FSS system using separate high-pass 34-GHz and 8.45-GHz FSSs and an X-band (7.2-/8.45-GHz) only option consisting of a single FSS. Conclusions are drawn and suggestions for future work prior to implementation are presented.
