I already have the part of mixing the signal with the 3GHz solved I had the output from the two HSMC outputs.
but, I didn't really get what you mentioned about converting to analog signal first .. because the case is to have the up converted signal inside the FPGA before it is sent to the HSMC output.

The signals on the HSMC outputs are digital values.
Is your 3GHz mixing logic digital (like one of the devices in the links above), or analog?
If the mixing is analog, then you would need an digital-to-analog conversion (DAC) of your 100MHz bandwidth signal, where the 100MHz bandwidth signal is possibly resampled to a 500MHz clock rate, or 1GHz clock rate signal, prior to analog mixing.
