Hi Laurent, I designed a Sigfox module in that we are using ATA8520E atmel IC,& I have configured the Mode and i'm getting the Device ID & PAC code, The problem is generating the RF signal i have used the SKY65378-11. In that I have to try to take the output but i Can't. Kindly share any other RF signal producer with replacement of SKY65378-11.

Hi, Changing the RF front end SKY65378-11 may involve with significant amount of work and RF design knowledge, you can also find alternative source form RFMW and TI, however let me know what design stage are you in now. Since you are not able to detect RF signal, so can you remove the SKY65378-11, with a SMA RF cable connect to ATA8520E RF output pin to a spectrum analyzer, are you able to see any thing transmitting? what is the frequency your design is operating?

I am using for uplink as 868.6 MHz (DPBSK Modulation) EU mode
and Dowlink as 869.65 MHz (GFSK Modulation) EU mode.
I identifying one point The PB0 of ATA8520E is used to enabling the FEM device. But I'm checking that pin always LOW. How can i Enable that pin as HIGH
