matlab-analyze-rf-amplifier

What problem does it solve?

It helps you evaluate RF amplifier behavior from S-parameter data by determining stability (unconditional vs conditional), selecting the right gain metric, and computing the reflection coefficients needed for matching design while validating passivity and causality.

Core Features & Use Cases

• Stability analysis: Compute Rollett stability factor K and Edwards-Sinsky mu to classify unconditional stability conditions across frequency.
• Gain evaluation: Calculate maximum available gain (Gmag), maximum stable gain (Gmsg), transducer gain, available gain, and operating power gain from appropriate source/load terminations.
• Matching-oriented outputs: Derive input/output reflection coefficients (gammain, gammaout) and simultaneous conjugate match coefficients (gammams, gammaml) for impedance targets.
• Data quality checks: Verify passivity and causality and handle common gotchas (e.g., Gmag NaNs for conditional stability, linear gain vs dB conversion).

Quick Start

Use the matlab-analyze-rf-amplifier skill to analyze stability, compute Gmag/Gmsg, and generate conjugate-match reflection coefficients from your amplifier S-parameters in a single workflow.
