The A1101R04C output power changes with ambient temperature. To obtain best possible
range and at the same time maintain certification compliance it is possible to trim the output
power as a function of temperature to maintain an approximate constant output power over
temperature. This can be done by changing the output power according to Table 6. The same
information is provided graphically in Figure 4. Note that the power level mentioned is the power
level one would measure at room temperature (i.e. the power level is in fact not increasing with
temperature, but is kept relatively stable when implementing this feature). If temperature
dependent control is not implemented the user must use the lowest power value for all
temperatures in order to maintain power within certification limits. A breakdown of the
temperature levels is given below for each Duty Cycle operation.
