Product Number: ADF5901
Hello, I would like to ask whether the output power adjustment of the ADF5901 is controlled through Register 1, specifically DB12~DB5? Does 0 correspond to -20dBm and 255 correspond to 8dBm? Is the adjustment evenly spaced? If I want to set the output power to around 0dBm, should I set it to approximately 183?
I plan to connect a power amplifier (PA), the HMC863ALC4, to the output. This amplifier has a gain of 24dB and a P1dB output of 27dB. Therefore, setting the ADF5901 output to 0dBm seems more appropriate. Would this approach be feasible?
Additionally, do I need to adjust the AUX BUFFER GAIN in the ADF5901? What is its function?
