Optenni Lab's matching circuit generation is fast and easy to use. You do not need any impedance matching or circuit simulation skills to optimize matching circuits in Optenni Lab. You can generate matching circuits in less than ten seconds using the four steps at right.

Within seconds, Optenni Lab creates, optimizes and ranks a number of circuit topologies. For each generated circuit, Optenni Lab shows the circuit topology, the S parameters of the matching circuit and the input impedance on the Smith chart.

In matching circuit generation you can also:

• Take into account losses in matching circuit components
• Use inductor and capacitor models from a component library
• Specify the topology manually
• Fix some component values
• Set upper and lower limits for the component values
• Carry out tolerance analysis
• Tune the generated circuits interactively

In manually created topologies you can use the following components:

• Inductors
• Capacitors
• Resistors
• Transmission lines
• 2-port S parameter blocks (e.g. accurate component models)

The components can be placed in series and parallel or inside hierarchical parallel and series resonators. Thus it is possible to define and optimize quite complex matching circuit topologies.

For each frequency range in the pass band, a different target level for efficiency can be specified. In addition, stop band attenuation targets can be given.

Note that matching circuit generation works with arbitrary frequency-dependent complex termination impedances. The S parameters of the circuit are calculated using the theory of power waves, which correctly describes the propagation of power in the matching circuit.
