RFD900+ Telemetry Modem
Hardware manual here.
- Same form factor and main pins as compared to the original RFD900.
- New LNA with higher gain and high IP3 for high interference environments. Approx 1-2dB higher sensitivity compared to original RFD900.
- Updated CPU with double the RAM and Flash compared to RFD900.
- AES Hardware accelerated encryption support *software still in development for this *
- Fully ESD protected + filtered - Every IO port is protected and filtered. Has passed preliminary CISPR 22 radiated emissions testing at an accredited test lab.
- Thicker PCB for extra mechanical strength.
- On board voltage regulation for all circuits compliant with FCC modular approval.
- Long range >40km depending on antennas and GCS setup *80km demonstrated by Edge Research labs on a balloon !, 57km in India, on Dipoles.
- 2 x RP-SMA RF connectors, diversity switched.
- 1 Watt (+30dBm) transmit power.
- Transmit low pass filter.
- > 20dB Low noise amplifier, high IP3 (Updated on RFD900+)
