The RFD900 Radio Modem is a high powered 900Mhz, ISM band radio modem designed for long range serial communication. Ranges of 15km and much higher have been reported. Many common autopilots have telemetry port current limits that prevent directly powering RFD900 radios at their full transmit power.

RFD900 provides compact and yet powerful data communication. The key features are: No configuration required for out of the box RF communications. The RFD900 is designed to be compliant to AS4268:2012, and FCC 15.247. It has not been certified as a standalone modem and should be compliance tested in the final product. 3. Power Levels.

The FCC limit for EIRP is 4 Watts, or 36dBm for frequency hopping radios in the ISM 900 MHz band. The Australian EIRP limit is 30dBm as defined by ACMA. 2-1 can be used to con vert the power in dBm into

New Processor, ARM 32 bit core. Air data rate: 500kbit/s. AES Hardware accelerated encryption. *Fully working* RC PPM Passthrough with telemetry at the same time. Fully ESD protected + filtered - Every IO port is protected and filtered. Original SiK point to point firmware implemented.

RFD900x provides compact and yet powerful data communication. The key features are: No configuration required for out of the box RF communications. The RFD900x modem is compliant to AS4268:2012, NZ GURL 2017, FCC 15.247 and RSS-247 Issue 2. Only the region locked versions of the modems are compliant.

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:

jDrones 和 RFDesign 推出了一款兼容 SiK 的长距离数传电台。 这个电台配合普通天线可以提供最少5公里的稳定链接。 jDrones have productized RFDesign modems (added a casing with power management, filtering and other electronics inside, along with cables to connect to popular flight controllers, and individually validated antennas).
