5G Epa Slope For Temperature Compensation (0Xf2H~0Xf5H); 5G Epa Temperature Compensation Limit(0X53H~0X54H) - MEDIATEK MT7612 Manual

i. Thermal sensor value: This value will be filled in MTK FT production line.
Customers don't need to re-fill this column.
2.37 2G/5G ePA Slope for Temperature Compensation
(0xF2h~0xF5h)
Offset Description
0xF2 5G ePA NT to high temp slope
0xF3 5G ePA NT to low temp slope
0xF4 2G ePA NT to high temp slope
0xF5 2G ePA NT to low temp slope
1. Fill up 2/5G ePA NT to high temp slope and NT to low temp slope value with positive value slope
2. If Slope value equals to 0x00 or 0xFF, temperature compensation will be disable
3. Unit of Slope: (℃/dB)
Example:
If gain difference between NT and HT is 4dB, the slope of +25 degree C to 85 degree C is equal to 15
(85-25)/4=15(dec)=0x0F(hex)
If gain difference between NT and LT is 5dB, the slope of +25 degree C to -20 degree C is equal to 9
((25-(-20))/5=9(dec)=0x09(hex)
If you use MTK HDK, you could use value as follows.

2.38 2G/5G ePA Temperature Compensation limit(0x53h~0x54h)
Temperature compensation will be constraint within Temperature compensation configures in
0x53h~0x54h. Resolution is 1dB/step.
1. Use 0x53[7:4] for 2G temperature compensation upper limit for high temperature gain
variation
2. Use 0x53[3:0] for 2G temperature compensation lower limit for low temperature gain variation.
3. Use 0x54[7:4] for 5G temperature compensation upper limit for high temperature gain
variation.
