    Hello,

    IF frequency is a function on receiver bandwidth setting. What setting are you using?

    Ok, thank you.

    i have EVB 1312R1,imaje rejection(-500kHz offset from wanted signal) is ~27dB.

    set up is : -95dBm wanted signal,  RX BW=118KHz.

  • In reply to Michael Ishakbaev:

    The default IF frequency is found in the user guide on page 2029.

    www.ti.com/.../swcu185a.pdf

    It also includes a small discussion about how to override the default values.

    Are you looking for image rejection performance on the device?
