Note:
1. Supported transmit power levels are determined by the ordering part number (OPN). Transmit power ratings for all devices cov-
ered in this datasheet can be found in the Max TX Power column of the Ordering Information Table.
2. Typical value marginally passes specification. Additional margin can be obtained by increasing the order of the harmonic filter.
