4.1.3.3 RF_OUT Matching

The following tables show the optimized transmit matching elements of RF_OUT to Ant1 without and with SPDT, respectively. The component values have to be changed without and with SPDT to take the capacitance and inductance of the switch and the parasitics on the application board into account. A separate matching network has to be applied for each output power and output frequency.
