[Discuss-gnuradio] Need info regarding USRP Front End protection/vulnerability

[William L. Bahn]

We will be using the USRP in an environment where it will be engaged by 
an Electronic Attack system capable of putting out about 40MW of EIRP in 
the form of pulses that are on the order of 4ns (possibly longer) but 
with very fast rise times on the order of 500ps. Our system will be 
using just the simple vertical whip antennas sold by Ettus. We are 
looking at using pretty much all of the Flex series of daughterboards 
and possibly the XCVR2450 and WBX boards as well.

What I need to determine is what the maximum power is that can be 
present at the antenna in order to avoid damaging the front end so that 
we can determine the minimum range to the jammer during the exercise.

Thanks.
