Additional variation may be experienced if the DC input Voltage and temperature changes
while the module is operational.
This chart shows the typical transmit output variation over frequency. The typical variation
is less than +/-0.5 dBm for all transmit levels, across the entire frequency band.
DC Input Voltage also affects the transmit output level accuracy. The typical variation is
less than +/- 0.20 dBm except at high RF output levels for low DC input voltages, as has
been discussed in the RF Power Output Impact on DC Input Current and Power
section.
The following chart shows the accuracy of the RF power setting across all supported input
DC voltages. Note that the actual RF output level starts to drop for +27 dBm output level
