FAQ

Q1: Whether a directional antenna is required for optimal signal reception. or omni antenna?

A1: It is better to use one fiberglass omnidirectional antenna and one ăng-ten định hướng phẳng.

1. Frequency Band Requirements

• băng tần L & S-band Support
  • Dual-band operation is required, likely for satellite communications, rađa, or airborne datalinks.
  • Clarify specific frequency ranges (e.g., băng tần L: 1–2 GHz, S-band: 2–4 GHz) and ensure coexistence mechanisms (e.g., filters/duplexers) to prevent inter-band interference.

2. Bộ khuếch đại công suất (PA) Specifications

• 2×20W RF Output
  • Dual-channel architecture with independent 20W amplification per channel, enabling redundancy or simultaneous dual-band transmission.
  • Critical considerations: Thermal management (for airborne environments), PA efficiency optimization (e.g., GaN technology), and EMI/EMC compliance.

---

3. Interface Configuration

• Giao diện mạng
  • 2× RJ45 ports: Support 100 Mbps Ethernet throughput; verify protocol compatibility (e.g., TCP/IP, VLAN tagging if needed).
• Truyền thông nối tiếp
  • 1× bidirectional RS232 port: Ensure full-duplex operation for control commands or low-rate data transmission.

4. Performance Metrics

• Tốc độ dữ liệu: 100 Mb/giây
  • Requires high-efficiency modulation (e.g., 256-QAM, OFDM) and sufficient RF channel bandwidth.
• Max Range: 200 km
  • Perform detailed link budget analysis: Account for Tx power (20ở PA), tăng ăng-ten, receiver sensitivity, free-space path loss, and atmospheric/terrain attenuation (critical for L/S-band over 200 km).

5. Airborne Design Constraints

• Environmental Compliance
  • Meet DO-160 standards for vibration, sốc, nhiệt độ (-40°C đến +70°C), and EMI/EMC.
• Physical Integration
  • Nhỏ gọn, lightweight design compliant with aviation form factors (e.g., ARINC 600). Prioritize heat dissipation and power efficiency.

---

6. Key Challenges & Open Questions

• Application Context
  • Clarify use case (quân đội, commercial UAV, or manned aircraft). Are encryption or anti-jamming capabilities required?
• Certification
  • Confirm regulatory needs: FAA/EASA certifications (e.g., DO-254/178C) or military standards (e.g., MIL-STD-810).
• Tích hợp
  • Define interface compatibility (e.g., ARINC 429, MIL-STD-1553) with existing avionics systems.
• Antenna Design
  • Specify antenna type (directional vs. đa hướng) and mounting constraints.

Technical Recommendations

1. RF Link Optimization
   • Use adaptive modulation (AMC) and forward error correction (FEC) to balance data rate and range.
2. Quản lý nhiệt
   • Implement GaN-based PAs for high efficiency and integrate active cooling (e.g., liquid cooling or forced airflow).
3. Dự phòng & Độ tin cậy
   • Design dual-channel redundancy for mission-critical airborne operations.
4. nguyên mẫu & Kiểm tra
   • Conduct field trials to validate 200 km range under real-world conditions (e.g., độ cao, sự can thiệp).
