The desired output power is -10 dBm. Figure 24 shows how the PATABLE should look like in the two cases where no ramping is used (A) and when PA ramping is being implemented (B). In case A, the PATABLE value is taken from Table 30, while in case B, the values are taken from Table 32. PATABLE[7] = 0x00 PATABLE[6] = 0x00 PATABLE[5] = 0x00 PATABLE[4] = 0x00 PATABLE[3] = 0x00 PATABLE[2] = 0x00 PATABLE[1] = 0x00 PATABLE[0] = 0x26 FREND0.PA_POWER = 0 PATABLE[7] = 0x00 PATABLE[6] = 0x00 PATABLE[5] = 0x34 PATABLE[4] = 0x33 PATABLE[3] = 0x32 PATABLE[2] = 0x31 PATABLE[1] = 0x30 PATABLE[0] = 0x00 FREND0.PA_POWER = 5 A: Output Power = -10 dBm, No PA Ramping B: Output Power = -10 dBm, PA Ramping Figure 24: PA Ramping |
