SubTHz: Couche Physique Sub-THz & Formation de Faisceaux Extreme-MIMO

SubTHz développe la couche physique et les front-ends RF de 100 à 300 GHz pour des débits sans fil de 100 Gbps à 1 Tbps.

SubTHz High-Band Transceiver & Phased Array Architecture

140 GHz / 220 GHz InP power amplification and direct digital baseband synthesis

Central System: Ultra-High-Speed DAC/ADC - 128 GS/s 8-bit converters with analog-to-information processing

Network Nodes

  • Ultra-High-Speed DAC/ADC
  • Indium Phosphide (InP) Power Amplifier
  • Reconfigurable Intelligent Surface (RIS)
  • Sub-Degree RF Tracker

Architectural Protocol Layers

  • Spaceborne PHY/MAC Layer (3GPP Rel-17 TS 38.300): Doppler compensation, HARQ disabling, and timing advance extension.
  • Orbital Mesh Routing (CCSDS / Delay-Tolerant Networking): Dynamic topology routing over intermittent laser crosslinks.
  • Regenerative Core Processing (OpenRAN / 3GPP CU-DU Split): Onboard user plane function (UPF) local breakout.

Key Metrics: < 18ms (LEO Orbit-to-Ground Roundtrip) | 100 Gbps (Optical Crosslink Throughput) | ±48 kHz (Doppler Shift Compensation) | 99.999% (Orbital Constellation Availability)
