Correctly implemented impedance matching guarantees maximum or optimum signal power transfer from a signal source to a load. Clearly, it is essential for the correct operation of any modern electronic signal processing circuit (consumer electronics, industrial process control electronics, medical electronics, and most importantly telecommunication related electronics). Without correctly implemented impedance matching, a significant fraction of the incident signal (on the load) energy and power would be reflected back to the source.

Of the two types of impedance matching, broad and narrow band, the former is more important, as a significant fraction of electronic signal processing circuits operate over a frequency band or range, rather than a single frequency (narrow band). However, design calculations for both broad and narrow band impedance matching sub-circuits are complicated, multi-step, and therefore time-consuming and very error-prone. This is especially true for traditional broad band impedance matching schemes, which are governed by both conjugate matching (as in narrow band impedance matching) and the Bode-Fano inequalities that impose strict upper limits on the gain and bandwidth of the impedance matching sub-circuit. Similarly, traditional narrow band impedance matching techniques make extensive use of the Smith chart. Using a Smith chart to extract meaningful results requires a high level of proficiency – a result of years of use. All the complexities of impedance matching sub-circuit design calculations arise from the frequency dependency of the reactance (“resistance”) of both the capacitor and inductor. To complicate matters, the most load impedances are complex, that is, consist of a parallel or series capacitor or inductor with a resistor. Although some extremely powerful and effective design schemes (Zobel sub-network, active impedance matching) are used to neutralize or nullify the frequency dependency of capacitor and inductor reactances, design calculation complexity is reduced only a little.
