Hi sir

In the 433M EVB measured output power values (the following two blue curve) and the Division I ADF7012 sample test,Adjust the register R2 DB11 ~ DB5, a total of 64bit, the output power changes are not as described in the 0.4dB steps spec, you also need to adjust the other settings and the last two low-power outputs (-15 dBm & -20 dBm) have a 5 dBc difference? Can you help improve the nonlinear 0.4dB problem.
