RFDesign RFD900x Modem US FCC Approved Version
by RFDesign

Introducing the RFDesign RFD900x-US Modem, an FCC-approved, high-performance telemetry solution designed for long-range communication applications. Operating within the 902–928 MHz frequency band, this modem is ideal for unmanned aerial vehicles (UAVs), ground robotics, and other remote systems requiring robust data links.

Key Features:

• Extended Range Communication: Achieve line-of-sight distances exceeding 40 km, with documented cases reaching up to 80 km, depending on antenna configuration and environmental conditions.
• High Data Throughput: Supports air data rates up to 224 kbps, ensuring efficient and rapid data transmission.
• Enhanced Security: Incorporates AES hardware-accelerated encryption for secure data communication.
• Simultaneous RC Control and Telemetry: Enables RC PPM passthrough alongside telemetry data, streamlining control and monitoring processes.
• Robust Design: Features fully ESD-protected and filtered I/O ports, dual RP-SMA RF connectors with diversity switching, and a compact, lightweight form factor.
