I designed a SIGFOX device the frequency of 868 MHz to 930 MHz, In that device I'm struggling at RF signal generating. I interfaced the ATA8520E with Arduino uno through SPI Communication. And i'm getting the ID & PAC code from ATA8520E. I'm From India so we didn't have any sigfox base stations. I brought a SIGFOX emulator for testing the Sigfox module. Kindly guide me,after getting ID & PAC code from ATA8520E what are all steps I can follow. If it is possible kindly share the circuit diagram after the part of ATA8520E. & share what type of RF modulation is occurs?

First the architecture or the ATA devkit is available online - check Microchip website.
You should follow exactly the reference design they suggest.
In regards to modulation, everything is stored in the System on Chip already so no need to recreate it.
