SATCOM Wideband Digital Channelized Receiver System-on-Chip (SoC) with Low-cost Silicon Technology

ABSTRACT: Recent demand for broadband satellite communications (SATCOM) has risen sharply for both the defense and commercial sectors. Tactical SATCOM, such as WGS, AEHF, and GBS, require increasingly high capacity to support DoD's C4ISR requirements, while on the other hand, civilian applications require high capacity to support high definition multimedia broadcasting, and high-speed internet access. To support the increasing demand in capacity, SATCOM payloads must provide wideband transponders to allow SATCOM terminals to communicate over multiple beams and multiple bands with channelized fan-out multicast and fan-in aggregation capabilities. In this SBIR, a low-cost, dual-band uplink receiver will be developed for the RF downconversion, digitization, and channelization of uplink SATCOM signals. The receiver will be radiation hardened to support a geosynchronous payload with a 15-year mission with total ionizing dose of 30 krad(Si). BENEFIT: The proposed work will significantly reduce the SWaP of SATCOM payloads while enabling higher capacity SATCOM networks.
