RFD900ux
The RFDesign 900uX is a long range telemetry radio modem, covering the 902-928 MHz frequency band.
Designed for long range serial communications applications with stringent requirements on size and weight.
The RFD900ux radio modem is designed, tested and inspected in Australia and is NDAA compliant.
The US variant is compliant with United States of America regulations.
Models:
| Modem Model | Maximum Transmit Power(dBm) | Frequency Band/s (MHZ) | Max No. of Channels | Max Duty Cycle (%) |
| 900ux | 30 | 902-928 | 51 | 100 |
| 900x-US (USA, CA) | 30 | 902-915 and 915-928 | 51 | 100 |
Key Features:
- A digital modem for long-range data transmission in applications with strict weight and size limitations.
- Compatible with the MAVLink message protocol.
- Maximum Air data rate: 224kbit/s.
- AES Hardware accelerated encryption.
- Optional RC PPM or SBUS Passthrough. (SiK firmware)
- GPIO Pin Mirroring capability. (SiK firmware)
- RF front-end filtering.
- ESD-protected and filtered IO pins.
- Firmware options available to achieve several network topologies including point-to-point SiK, Multipoint (MP) mesh and Asynchronous mesh.
- User updateable firmware and parameters.
- Smallest, lightest radio modem in class.
- License-free use in USA and Canada (US variant).
- Compatibility with x series modems.
Note:
- The ux and x series modems are not compatible with older "a" or “+” series modems .
Interfaces:
- RF : 2x u.FL RF connectors
- Serial: Logic level TTL (+3.3V)
- Power: +5v, ~1A max peak (at maximum transmit power)
- GPIO: General purpose IO (Digital capable).
Compliance:
- Regional version modems are compliant with regional regulation
- NDAA compliant
- FCC Part 15.247 (Frequency hopping and digitally modulated intentional radiators)
- AS/NZS 4268:2012 (Radio equipment and systems – short-range devices
Note:
- Regionally locked version of the modems may restrict or limit the performance and available parameter settings compared to the unlocked modems.
- Ultimately it is up to the user to identify the radio frequency regulation applicable to their areas of operation and ensure their modems parameters are set correctly.
