New Modem Chip for LEO, MEO and GEO from SatixFy

SatixFy Space System has announced a new modem chip to be used over LEO, MEO and GEO systems, with appropriate doppler and fade profile performance.

The Sx3099 hosts 1 to 8 modems with aggregated throughput of 1 Gsymb/sec in both Tx and Rx directions. A single Sx3099 chip provides a single 1 Gsymb/sec carrier 2 X 500 Msymb/sec “make before break” handover in LEO aero connectivity, 8 X 125 Msymb/sec or any combination of channels aggregated to 1 Gsymb/sec.

This is the first chip to fully support the entire DVB-S2X standard including all Beam Hopping modes as defined in the 2019 revision annex E. On top of previously defined formats, the chip includes all the new Super-frame format types 5, 6 and 7 (“point and shoot” Beam Hopping). Sx3099 includes native support for DVB-RCS2 400MHz transmission as well as complete Software Defined Radio (SDR) for any other waveform.
