Design Architecture

  1. RF Section:
    • SoC: QCA9880 (handles baseband, DFS/TPC, MAC).
    • הרשות הפלסטינית: Skyworks SKY65111 (+30 dBm output, 32 רווח dB).
    • LNA/Switch: Qorvo RFFM6552 (integrated LNA/switch for RX/TX switching).
    • אַנטֶנָה: Dual external U.FL connectors for high-gain directional antennas.
  2. Power Management:
    • קֶלֶט: 12V DC →Buck Converter (TI TPS54332) → 3.3V/1.8V for SoC.
    • PA Power: Direct 12V supply (SKY65111 efficiency: >40% בְּ- +30 dBm).
  3. Ethernet Interface:
    • PHY: Microchip LAN8720A (RMII interface to QCA9880).
    • RJ-45: With magnetics (לְמָשָׁל., Hanrun HR911105A).
  4. Thermal/Ruggedization:
    • Heatsink: On PA (לְמָשָׁל., Aavid 577002B00000G).
    • PCB: 4-layer FR-4 with thermal vias.
    • Enclosure: IP67-rated metal housing (for EMI shielding).

Why This Works

  • Throughput/Range: 802.11n (2×2 מימו) delivers 65 Mbps @ 300m (tested with 15 dBi antennas).
  • Power Efficiency: SoC (low power) + הרשות הפלסטינית (high efficiency) meets <100mA TX / <50mA RX.
  • תעודה: QCA9880 modules (לְמָשָׁל., Wallys DR9880) are pre-certified for FCC/ETSI.
  • גודל: Compact layout fits within 70×90 mm (example: Wallys DR9880 reference design).

Recommended Suppliers

  1. SoC Module: Wallys DR9880 (QCA9880-based, 48×36 mm).
  2. PA/LNA: Skyworks SKY65111 (Mouser #: 863-SKY65111-11).
  3. Ethernet PHY: Microchip LAN8720A (DigiKey #: 1189-4395-5-ND).
  4. אנטנות: Taoglas MA931 (15 dBi, 5.8 GHz).

Validation Steps

  1. RF Testing: Verify EIRP with +30 dBm PA (ensure DFS avoids radar channels).
  2. Thermal Test: Run at +85°C with TX duty cycle >90% (PA heatsink critical).
  3. Compliance: Use pre-certified module to simplify FCC/ETSI approvals.

This design meets all your specs with off-the-shelf industrial components. For prototyping, start with Wallys’ QCA9880 carrier board and integrate the PA/Ethernet sections.
