In addition to general matching circuit optimization, Optenni Lab calculates two-component matching circuits that obtain conjugate matching to the generator impedance at a single frequency (critical coupling) or maximize the bandwidth around the starting frequency at a given matching level (overcoupled matching). Either the total bandwidth or the symmetric bandwidth around the starting frequency is maximized. Also the two-component matching circuit generation works with an arbitrary frequency-dependent complex termination impedance. When the termination impedance is real (e.g. 50 Ohm), an exact match can be obtained at a single frequency.

The difference between the two matching circuit generation approaches in Optenni Lab is that the general matching circuit generation tries to obtain as good matching as possible over a given frequency range and a given number of components, whereas the two-component matching tries to maximize the bandwidth at a given matching level.

The conjugate matching and symmetric bandwidth maximization procedures are used in the calculation of the bandwidth potential.
