Application Schematic 1
Optimized for Efficiency at 4.8V
This schematic defines the optimum configuration for maximum efficiency at 4.8V. Under these conditions, as can be
seen in the data plots, the power drops at 4.0 V. Over 70% power-added efficiency can be achieved at +30.8 dBm with
4.8 V and +8dBm input level with this implementation.
