RF Toolbox and RF Blockset

Design, analyze, and simulate RF systems in MATLAB -- from measured S-parameter data through full time-domain Circuit Envelope simulation. One unified workflow covering passive networks, active device characterization, system cascade budgets, and behavioral time-domain modeling.

When to Use

Measured data workflows

• Loading Touchstone files (.s1p through .snp), validating quality (passivity, causality, IEEE P370)
• Plotting on Smith charts and rectangular plots, interpolating, re-referencing impedance
• Converting between S, Z, Y, ABCD, T, H, G parameters; computing mixed-mode differential
• Cascading and de-embedding S-parameter networks; fixture removal

System design and analysis

• Building RF signal chains from behavioral elements (amplifier, modulator, rffilter, nport, etc.)
• Computing cascaded gain, noise figure, IP3, SNR, output power with rfbudget
• Comparing Friis vs Harmonic Balance solver accuracy
• Exporting to RF Blockset Simulink models, Communications Toolbox, or MATLAB scripts
