Bandwidth is a precious commodity, particularly in the frequency bands used by military satellite communications (SATCOM) systems. In this multi-phase SBIR program, TrellisWare proposes to develop, demonstrate, and deliver programmable RF transceiver technology that will allow the bandwidths of multiple SATCOM links to be used in parallel as if they form a single, wideband channel. Our solution will enable the spectrum that is currently available in the L and C through Ka bands to be used in a much more bandwidth-efficient manner by existing and future wideband SATCOM systems.
