They transmit the energy from input to output by a transmission line mode instead of by flux linkages as in the case of conventional transformers.
When properly designed, they can have extremely high efficiencies and very broad bandwidths. The theory of operation of these devices rests chiefly on that of chokes and transmission lines. A balun or unun is simply a choke that isolates the input from the output thus only allowing transmission currents to flow and a configuration of transmission lines. A major difficulty even today is that this very important and popular class of matching devices is not included in the curriculums at universities.
In fact, there are no standards for the specification and testing of these devices by any professional group! As a result, practically everyone still perceives these devices as conventional transformers and not transmission line transformers. To remedy this, it has been suggested that this class of transformers be called broadband transmission line matching networks.
