ADF5902: Peak Transmit Power

Hi,

We are currently developing a product with the ADF5902 in 24GHz ISM band and want to verify the peak transmit power based on the Datasheet/our measurements. From what we measured on our spectrum analyzer we got a max power of 8.5dBm while the datasheet states typical power is 8dBm. On the datasheet it states the Max transmit power is 12dBm about 4dBm difference from the max programmable power, When is this max transmit power achieved? We want to make sure we meet FCC requirements in the Band.

Thanks,

Jacob
