Typical I/O Circuits
Transmit Power
The module is able to adjust transmit power from 29.5 dBm to
10.5 dBm, configurable in 1 dBm steps with an accuracy (the measure
of the power output for each level) of +/-0.5 dBm. The initial tolerance
(the measure of the power output for each level) is +/-0.5 dBm. The
output power is set on each of the antennas. Output power tolerance
from the nominal setting is +/- 0.75 dBm over an ambient
temperature range of -20 °C to 60 °C.
