Hi!
We bought the RDAS kit for our experimental rocket here at Université
Laval. We are now designing a new type of antenna for our system, and
transmitted power seems to be an issue.
We bought the kit 2007 AED R-DAS xmit V2.1 #01447. On the R-DAS web
site, we saw that the Linx amplifier BBA-519-A should give us up to 50mW
of transmitted output power. However, on a spectrum analyzer, we only
measure up to -22 dBm channel power between 910-930 MHz (we're using
channel 7) which is about 6microWatt...in our tests, all the impedances
were adapted.
We just saw on the module 3 pins that aren't connected or jumped. Are
those should "jumpered" to operate the amp ? Here's a pic of our system.
If you have the connection diagram or a datasheet of how the module
should be operated, it would be great: the system we have was bought a
couple of years ago, and the original team members are not here anymore,
and that's why we have such nOOb questions :)
Thanks!!
