a. The cellular standards listed indicate only typical usages of that band in some countries. Other standards may
also be used within those bands.
b. Derate by 1.5 dB for temperatures less than –10°C or more than 55°C, or voltages less than 3.0V. Derate by 3.0
dB for voltages of less than 2.7V, or voltages of less than 3.0V at temperatures less than –10°C or greater than
55°C. Derate by 4.5 dB for –40°C to –30°C.
c. TX power for Channel 1 and Channel 11 is specified by non-volatile memory parameters.
