Application Data External matching
*The 50 Ohm match of the input and output ports of the TQP2420G is completed by the addition of a small number of external components. The optimum impedance presented to the respective ports is described in the Smith Chart plot at the right. *The impedance shown can be achieved by a number of topologies. The preferred topology selected for Triquint 242x evaluation board is shown in the schematic.
