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.
