RampTime defines the PA power ramping time. The Ramp Time can be set from 10 us to 3400 us according to the
following table:
Table 9-6: RampTime
RampTime
SET_RAMP_10U
SET_RAMP_20U
SET_RAMP_40U
SET_RAMP_80U
SET_RAMP_200U
SET_RAMP_800U
SET_RAMP_1700U
SET_RAMP_3400U
A value of Ramp Time value of 40 us allows the best trade-off between a fast RF power establishment and the minimum RF
spurious, therefore a compliance to the radio standards.
