Product data
SA2411
The last 5 curves are characterization data for supply voltage, temperature and power. The worst-case scenario is the combination of highest
temperature/lowest supply. The best-case scenario is the combination of lowest temperature and highest supply voltage. The data has been
taken using a non-modulated carrier at 2.5 GHz.
