SubTHz: 서브 테라헤르츠 물리 계층 및 초거대 MIMO 빔포밍 설계

SubTHz는 100 GHz~300 GHz(D-대역 및 G-대역) 물리계층, RF 프론트엔드 및 안테나 어레이를 설계하여 6G 및 항공우주 환경에서 100 Gbps~1 Tbps 무선 전송을 구현합니다.

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)
