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.
Using raised cosine filtering with an alpha = 0.7. The inner frequency deviation = 1.78 kHz, and the POST_DEMOD_BW = 24.6 kHz.
For the definition of frequency deviation, refer to the Register 2—Transmit Modulation Register section.
Measured as maximum unmodulated power.
Conductive filtered harmonic emissions measured on the EVAL-ADF7021DBx, which includes a T-stage harmonic filter (two inductors and one capacitor).
For matching details, refer to the LNA/PA Matching section.
