Note 5:
LOG-Linearity Error is the input-referred power measurement error value. Input power 0dBm. For higher load impedance the turn-off time relative to the best fit straight line (output voltage vs input power in dBm) will be (much) larger as the OUT interface is high impedance in shutdown obtained by linear regression at TC = 25°C. The input power range used mode. for the linear regression is from –37dBm to –5dBm for all frequencies. An offset of 0.5dB is added to the LOG-intercept for all frequencies to center the errors over the full temperature range.
