1. The cellular standards listed indicate only typical usages of that band in some countries. Other standards may also be used within those
bands.
2. TX power for channel 1 and channel 11 is specified separately by nonvolatile memory parameters to ensure band-edge compliance.
3. Optimal RF performance, as specified in this data sheet, is guaranteed only for temperatures between –10°C and 55°C.
