3. To avoid yield problems with the power template and switching transients spectrum a margin to the
compression point of the PA should be observed. However, the output power must be kept within
the tolerances specified in Table 10-5.
4. Store DAC values in memory (GD_FullPower_Band).
5. Initiate the intermediate value calculation, which calculates and store the values in memory
(GD_IntermediatePower_Up/Down_1..7_Band).
6. The difference between the transmitter power at two adjacent power control levels, measured at the
same frequency, shall not be less than 0.5 dB and not more than 3.5 dB.
