Technology considerations in EHF Satcom systems
Abstract
The history of mm-wave communications is reviewed briefly and technological requirements for future implementation of mm-wave communications satellites for military and commercial applications are surveyed. The driving force for expanding mm-wave usage is an impending saturation of the GEO arc over North America with C- and Ku-band Satcoms. For military purposes, 44 GHz operations would provide antijamming capabilities and on-board processing. Necessary developments for the mm-wave Satcoms include scanning and multiple beam antennas, low-noise amplifiers, filters which channelize the frequency band, frequency hopping synthesizers, QPSK and MSK modulation systems and improvements in GaAs and indium phosphide ICs. Finally, digital systems are being explored for commercial integrated global data, voice and video systems.
