Arria V FPGA RF Development Kit: Does Not have any SMA GPIO I/O OUTPUT

You cant use the high speed transceiver pins as general purpose I/O.

If you want to send a signal out from those, you would need to instantiate a minimal transceiver IP core and all the required PHY/reconfig controller/etc. You then send the data out using the PCML differential standard and have a non-ac-coupled CML to TTL (or CMOS) IC at the other end.
