When matching impedances, it is not always economical to use a wound transformer. For instance, if the power loss is trivial, two resistors will normally be the right approach. However, if the power loss is significant, then another circuit (the Lpad) can match impedances with minimal power loss.
If moderate spectrum shaping is important, a \(\pi\) or T network might be more appropriate. If significant spectrum shaping is important then cascading \(\pi\) or T networks is a good approach. \(\hspace{18.9cm}\)
