    Thread Summary
    
                The user is developing a Data Radio using the ADF7021 with 2FSK modulation and a 24 kbps data rate, currently achieving a minimum SNR of 10 dB. The final answer suggests checking the LNA/Mixer Modes on page 31 of the datasheet to potentially lower the SNR. The user has already tried adjusting the AGC GAIN, but it increased noise.

    Hi,
    

    

    I am developing Data Radio by using ADF7021 with modulation 2FSK and 24 kbps data rate and already working but I still have the SNR minimum at 10 dB, Is it possible to make SNR below 10 dB like 5dB? if yes how to do that? For information I made Frequency deviation 6 KHz.
