1 Using Gaussian or raised cosine filtering. The frequency deviation should be chosen to ensure that the transmit occupied signal bandwidth is within the receiver
IF filter bandwidth.
2 Using raised cosine filtering with an alpha = 0.7. The inner frequency deviation = 1.78 kHz, and the POST_DEMOD_BW = 24.6 kHz.
3 For the definition of frequency deviation, refer to the Register 2—Transmit Modulation Register section.
4 Measured as maximum unmodulated power.
5 Conductive filtered harmonic emissions measured on the EVAL-ADF7021DBx, which includes a T-stage harmonic filter (two inductors and one capacitor).
6 For matching details, refer to the LNA/PA Matching section.
