SatixFy is addressing all future trends in the terminal market
• Lower cost - ASIC based solutions such as the SatixFy Out-Door-Unit, or In-Door-Terminal “SIDU”. ASIC high integration allowing affordable VSAT terminal solutions
• Higher Throughput– single carrier 500MHz (no Backoff). In the future (2019), 1GHz carrier Rx and Tx to support UHTS satellite
• Beam-Hopping - Higher Satellite and terminal capability towards users
• Interoperability - flexibility with SDR ASICOperators want to escape from proprietary solution - VSAT terminal should be interoperable and future-proof
• Mobility -> addressed with our Active Flat Panel Array Antenna terminals in Ku and Ka band. Customers want to receive content anytime, anywhere (Land, Sea, Aero)
SX-3000
Lower cost terminal trend
Indoor Unit (S-IDU)
• Miniature L-band IDU
• Ready for Ku/Ka
• SX-3000 based board
• FWD: S2X - RTN: RCS2, S2X
• HTS modem unit
• 7.5cm x7.5cm
• Low Cost
• Units in volume now
Outdoor Unit (S-ODU)
• 2-way terminal, Fully Outdoor
• S2X FWD, S-M2M, or RCS2 RTN
• Wideband, high-performance
• Single PoE Cat5 cable
• Embedded modem SX-3000 ASIC
• Lowest cost approach
FLEXIBILITY & INTER-OPERABILITYwith S-IDU remote Terminal
• High Performance 125 MHz Operation
• DVB-S2X fully compliant
• DVB- RCS2 or SDR return channel
• Dual Gigabit Ethernet port
• Low power and affordable
• Small size
• Annex M – time slice support
• Annex E – beam hopping support
Flexible platform welcoming any third-party waveform componentFuture proof with Software Defined Radio ASIC
“Beam-hopping ready” terminals
• SatixFy's SX-3000 ASIC is the first to market with beam hopping support
• VSAT terminals based on the SX-3000 are available
• Full backwards compatibility to DVB-S2 and DVB-S2X without Beam Hopping
• The SX-3000 enables VSAT vendors to support DVB-S2X with beam hopping TODAY - future proof your network!
Satellite payload in BH mode
Ground network: hubs transmit DVB-S2X Super Frames and VSATs receive BH carriers
Beam-hopping benefits
• Beam Hopping provides best flexibility in allocating capacity to the beams with high traffic demand
• Reduction of the unmet and excess capacity by 40%
• Save on DC power by 50%
• Lower DC power terminal (20-40% savings)
• Best fit for mobility networks (air and maritime) with changing bandwidth demands
• Reduce risk uncertainty by increasing the coverage with reduced initial CAPEX

Beam-hopping emulator
Mobility with Active Flat Panel Array (AFPA) electronically steered antenna terminal• Modular design scalable to build small, medium and
large antennas and any number of beams
• Support different RF frequencies KU or KA using dedicated RFIC chips
• True Time Digital Delay enables:• wide band (500MHz)
• Multi-beam
• large scanning angle
• Embedded SX-3000 modem for power management (No data, no Power), calibration, and Time Duplex Division access scheme
• Multi-beam capable for LEO/MEO constellation - support make before break operation
• Applications: IoT, Aero, maritime, Land mobile IoT terminal
AERO terminal
Summary“the Change is Now”
• Software Defined Radio Baseband ASIC supports more traffic -500MHz now, and 1Ghz DVB S2X coming soon
• The SX-3000 SDR ASIC based on DSPs plus few fast and generic HW blocks enables platform flexibility and inter-operability
• The SX-3000 ASIC supports DVB-S2X with beam hopping TODAY => operators can future proof their network
• ASIC integration allows low power and affordable user-terminal
• Electronically Steered Phased Array Antenna based on True-Time-Digital Delay is the right technology for User Terminal mobility, especially when we speak about multi-beam, wide bandwidth, large scanning angle, and large antenna
