Design Architecture

1. 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).
   • Antenne: Dual external U.FL connectors for high-gain directional antennas.
2. Power Management:
   • Input: 12V DC →Buck Converter (TI TPS54332) → 3.3V/1.8V for SoC.
   • PA Power: Direct 12V supply (SKY65111 efficiency: >40% op +30 dBm).
3. Ethernet Interface:
   • PHY: Microchip LAN8720A (RMII interface to QCA9880).
   • RJ-45: With magnetics (Z.B., Hanrun HR911105A).
4. Thermal/Ruggedization:
   • Heatsink: On PA (Z.B., 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 MIMO) delivers 65 Mbps @ 300m (tested with 15 dBi antennas).
• Power Effizienz: SoC (low power) + PA (high efficiency) meets <100mA TX / <50mA RX.
• Zertifizéierung: QCA9880 modules (Z.B., Wallys DR9880) sinn pre-zertifizéiert fir FCC / ETSI.
• Gréisst: Kompakt Layout passt bannent 70 × 90 mm (Beispill: Wallys DR9880 Referenz Design).

Recommended Suppliers

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

Validation Steps

1. RF Testen: Verifizéiert EIRP mat +30 dBm PA (suergen DFS vermeit Radar Channels).
2. Thermesch Test: Run bei +85 ° C mat TX Duty Cycle >90% (PA heatsink kritesch).
3. Konformitéit: Benotzt pre-zertifizéiert Modul fir FCC / ETSI Genehmegungen ze vereinfachen.

Dësen Design entsprécht all Är Spezifikatioune mat off-the-shelf industrielle Komponenten. Fir Prototyping, Start mat Wallys 'QCA9880 Carrier Board an integréiert d'PA / Ethernet Sektiounen.
