Design Architecture
- RF Section:
- SoC: QCA9880 (handles baseband, DFS/TPC, MAC).
- PA: Skyworks SKY65111 (+30 dBm output, 32 dB gain).
- LNA/Switch: Qorvo RFFM6552 (integrated LNA/switch for RX/TX switching).
- アンテナ: Dual external U.FL connectors for high-gain directional antennas.
- Power Management:
- 入力: 12V DC →Buck Converter (TI TPS54332) → 3.3V/1.8V for SoC.
- PA Power: Direct 12V supply (SKY65111 efficiency: >40% に +30 dBmの).
- Ethernet Interface:
- PHY: Microchip LAN8720A (RMII interface to QCA9880).
- RJ-45: With magnetics (例えば。, Hanrun HR911105A).
- Thermal/Ruggedization:
- Heatsink: On PA (例えば。, Aavid 577002B00000G).
- PCB: 4-layer FR-4 with thermal vias.
- Enclosure: IP67-rated metal housing (for EMI shielding).
Why This Works
- Throughput/Range: 802.11NS (2×2 MIMO) delivers 65 Mbps @ 300m (tested with 15 dBi antennas).
- 電力効率: SoC (low power) + PA (high efficiency) meets <100mA TX / <50mA RX.
- 認証: QCA9880 modules (例えば。, Wallys DR9880) are pre-certified for FCC/ETSI.
- サイズ: Compact layout fits within 70×90 mm (example: Wallys DR9880 reference design).
Recommended Suppliers
- SoC Module: Wallys DR9880 (QCA9880-based, 48×36 mm).
- PA/LNA: Skyworks SKY65111 (Mouser #: 863-SKY65111-11).
- Ethernet PHY: Microchip LAN8720A (DigiKey #: 1189-4395-5-ND).
- Antennas: Taoglas MA931 (15 dBi, 5.8 GHzの).
Validation Steps
- RF Testing: Verify EIRP with +30 dBm PA (ensure DFS avoids radar channels).
- Thermal Test: Run at +85°C with TX duty cycle >90% (PA heatsink critical).
- 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.
