Impedance Matching Network Design

Design, evaluate, and optimize 1-port impedance matching networks. The matchingnetwork object and matchingNetworkDesigner app match a source impedance to a load impedance — they do not yet design 2-port (e.g., filter-style) matching. The object generates candidate topologies, ranks them by performance, and exports as circuit objects.

When to Use

• Designing L, Pi, or Tee impedance matching networks
• Matching a source impedance to a frequency-dependent load (antenna, filter)
• Ranking candidate topologies by return loss or transducer gain
• Converting lumped matching designs to transmission line stubs via Richards transformation
• Evaluating component tolerance sensitivity in matching networks
• Importing custom matching circuits for comparison

When NOT to Use

• Building general-purpose RF circuits with arbitrary topologies -- use matlab-compose-rf-circuit
• Composing rfbudget cascade elements -- use matlab-create-rfbudget-elements
• Analyzing amplifier stability or gain circles -- use matlab-analyze-rf-amplifier
