Re: [USRP-users] B210 - How much input power can its TX chains endure?

​Thank you for your quick answers, Nate and Marcus.

If we accidentally end up burning down one of our B210 we will let you know
where the empirical upper bound is at :)

​Cheers,
Brais.

Hello,

We are planning to use a B210 device in a project where there may be 
high power interferences.


What would be the *maximum input power through a B210 RF _output_*__to 
prevent damaging the device?
(The AD9361 datasheet indicates an absolute maximum of 2.5 dBm for an 
RF input, but it does not specify a similar value for RF outputs)

Given that the device can *produce* perhaps +7dBm, I would set that as 
the lower-bound on the energy that can be present at the
  TX antenna terminals.  If the datasheet doesn't specify, then I don't 
think anyone at Ettus has tested the upper bound.

Hi Brais,

You'll want to have an isolator/ciculator inline.
