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.
