RFD900, RFD900+ - New long range radio modem

Posted by Seppo on May 25, 2012 at 8:15am

Hi All,

I would like to introduce you to a new radio modem that we developed for very long range datalinks!

http://rfdesign.com.au/RFD900.php

Some of the key features of the RFD900 are as follows:

  • Multi point and point to point link capability.
  • Long range >40km depending on antennas and GCS setup.
  • 2 x RP-SMA RF connectors, diversity switched.
  • 1 Watt (+30dBm) transmit power.
  • Transmit low pass filter.
  • > 20dB Low noise amplifier.
  • RX SAW filter.
  • Passive front end band pass filter.
  • Open source firmware / tools, field upgradeable, easy to configure.
  • Small (30 x 57 x 13 mm), light weight (14.5g).
  • Compatible with 3DR / Hope-RF radio modules.
  • License free use in Australia, Canada, USA, NZ.

 

These modems are designed to support long range applications, while being easy to use and affordable.  

These modems have been flying in various platforms and have demonstrated excellent performance in real applications. 

RFD900 modems are now available at: http://store.rfdesign.com.au

Support within APM planner and the radio configurator from Michael Oborne is already available.

It works seamlessly with APM planner, all radio Mavlink parameters are available.

Update, December 2014:  The RFD900+ with improved specifications is available now at:

                  Thomas do you use Dropbox I do believe they are a very good sight for sharing photos .

                  Just send the Link of where the pictures are and one can view them.

                  It is a FREE App. that will install on Windows, Mac, or Linux

                    @James,

                    I am registered on both Dropbox and Google Drive, but I prefer Google Drive.

                  I don't understand why they won't let you view them as a member.

                  Most websites wants you to sign up as a member .

                  Do you know of any websites that will let you Paste Pictures that others can see ?

                  An then there is a time Limit before they will delete them.

    Hi Carl,
    I had something similar with the RFD900s. It turned out to be the voltage drop during each transmit burst. I had to add a 100uF cap right at the modem because the supply wires were a little small for the distance I ran them. Have you tried setting the power to minimum to see if it has any effect? It's just a thought anyway.
