LimeSDR Multiple Channel (2 Signals Tx/Rx)

Hello everyone

Has anyone successfully tried to transmit/receive I and Q signals on two different channels? Or even just two different signals? I have been exploring this matter for quite some time already, but can’t seem to find the solution.

My problem lies on the hardware I will connect on the LimeSDR Tx/Rx, an up/down converter to 60Ghz frequencies. Here’s the diagram, it only accepts I and Q signals seperated has input/output, and that I can do on GnuRadio, the only thing I can’t do is to transmit/receive them at the same time on the LimeSDR. GnuRadio is the framework I have been using, but I can look in other directions if more capable.

Thank you.
