Design Architecture

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

Why This Works

Throughput/Range: 802.11엔 (2×2 에도 불구하고) delivers 65 Mbps @ 300m (tested with 15 dBi antennas).
전력 효율성: SoC (low power) + 아빠 (high efficiency) meets <100mA TX / <50mA RX.
인증: QCA9880 modules (예를 들어, Wallys DR9880) are pre-certified for FCC/ETSI.
크기: 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 GHz의).

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.
