Can the existing firmware support that bandwidth? The 10Gbps Ethernet
can but I am not sure about the rest of the USRP. I own two of them
and have never tried to do that.

You can (theoretically) stream 200Msps from an X310 over 10GiGe. Getting
a 'pooter that can sustain that rate for
any length of time is.....challenging.

You're right - I completely missed that part of the email.
My apologies.

Yes, as stated in the original post 'Basic-RX with a minimum
of 1 MHz'. The DC is cutoff by the balun on the basicRX
making it unsuitable for IQ.

Hello,
I want to use an external IQ mixer with an external LO.
My signal is 160 MHz wide, which fits nicely into the
nominal complex 200 MHz Nyquist of the X310.
Unfortunately the only daughterboards for direct access to
the ADCs are LFRX which maxes out at 30 MHz, and the
Basic-RX with a minimum of 1 MHZ.
I am thinking of spinning a custom daughter board derived
from LFRX with a wideband differential driver such as
https://www.analog.com/media/en/technical-documentation/data-sheets/6406fc.pdf
or
alternatively just replacing the chip on an LFRX since
these appear to be footprint compatible.
Separately, I was looking at LFTX schematics and the part
# for the amplifier is not specified. Can somebody at
Ettus/NI save me some time and lookup that part #.
Comments?
Have you considered the BasicRX?
