3.1.5.4.2. The Tx power difference
The power value difference are between +7 and -8.
The value 0x0 ~ 0x7 in eFuse means 0 ~ +7 and the value 0x8 ~ 0xF in eFuse means -8 ~ -1.
The +1 power difference will plus 0.5dB power.
We take Table 7 as an example :
The 2G power difference are shown as below:
MCS7-B20 to MCS7-B40
(MCS7-B20_Tatget_Power - MCS7-B40_Tatget_Power)x2
= ((13 – 13) x2) = 0
54M-1T to MCS7-B40
(54M_Tatget_Power - MCS7-B40_Tatget_Power)x2
= ((14 – 13) x2) = 2
MCS15-B40 to MCS7-B40
(MCS15-B40_Tatget_Power - MCS7-B40_Tatget_Power)x2
= ((12 – 13) x2) = -2
