5. Pulling of Frequency due to ASK Modulation (PA Switching)
9128G–RKE–03/11
The switching effect on VCO frequency in ASK Mode is very low if a correct PCB layout and
decoupling is used. Therefore, power ramping is not needed to achieve a clean spectrum (see
Figure
Figure 5-1.

Typical RF Spectrum of 40kHz ASK Modulation at Pout = 12.5dBm
