a. The cellular standards listed only indicate the typical usages of that band in some countries: other standards
may also be used within those bands.
b. Derate by 1.5 dB for –30°C to –10°C and 55°C to 85°C, or supply voltages lower than 3.0V. Derate by 3.0 dB
for supply voltages of lower than 2.7V, or supply voltages lower than 3.0V at –30°C to –10°C and 55°C to 85°C.
