Design Architecture

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

Why This Works

• Throughput/Range: 802.11VCAN1321 (2×2 Μίμος) delivers 65 Mbps @ 300m (tested with 15 dBi antennas).
• Power Efficiency: SoC (low power) + PA (high efficiency) meets <100mA TX / <50mA RX.
• Πιστοποίηση: QCA9880 modules (Π.χ., Wallys DR9880) are pre-certified for FCC/ETSI.
• Μέγεθος: 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. Antennas: 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.
