SIMULATION / SA-KNOW-RF-SPARAM-001
RF S-parameter and de-embedding evidence replay
RF reference-plane replay
Compare intrinsic complex S-parameters with passive fixture embedding, four correction classes, residual-error sensitivity, stability/passivity screens, fT/fmax proxies, and a bounded noise-parameter equation.
EXPLORE
Start with the observable.
Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.
- Choose an assumed small-signal device, passive fixture, correction method, deterministic residual-error state, and reference impedance.
- Compare raw and corrected complex S21, return loss, fixture insertion loss, and corrected-to-intrinsic error across 1-100 GHz.
- Read fixture sigma-max separately from active-device K and Delta, then keep the linear two-port and sparse-band limitations attached.
- Use fT, fmax, current-gain, and noise-factor outputs as equation-literacy screens before naming the owned data and review needed for a real claim.

RUN CARD
Conditions before conclusions.
The browser filters a saved CSV. It does not control a VNA, ingest Touchstone files, execute calibration or IEEE 370 software, run EM/SPICE/compact-model solvers, recommend matching, or issue RF signoff.

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Generate a deterministic 3 x 4 x 4 x 3 x 2 x 21 Cartesian sweep over assumed device state, passive fixture, correction method, residual-error state, real reference impedance, and frequency.
Keep this method attached when reusing the figure or metric.
Build an original small-signal Y matrix, convert it to complex S-parameters, cascade passive positive-delay ABCD fixture boxes, and compare four explicitly bounded reference-plane correction classes.
Keep this method attached when reusing the figure or metric.
Recompute fixture singular-value passivity, corrected two-port K and Delta, first-order fT/fmax screens, and a synthetic four-noise-parameter equation at each frequency.
Keep this method attached when reusing the figure or metric.
Preserve calibration, de-embedding, passivity, causality, uncertainty, compact-model, measurement, and RF-owner replacement evidence as separate gates.
Keep this method attached when reusing the figure or metric.
LIMITS
What this page does not claim.
The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.
The replay contains 6,048 original deterministic rows, zero measured rows, zero copied Touchstone files, zero external device values, and zero proprietary model or PDK files.
Carry this boundary into any derivative note, paper draft, or slide.
The symmetric split-fixture and port-extension methods are teaching proxies, not IEEE 370 compliance, multiline TRL execution, VNA calibration, or measurement correction software.
Carry this boundary into any derivative note, paper draft, or slide.
K and Delta are linear two-port screens; fixture sigma-max is a pointwise analytic passivity check. Neither establishes broadband causality, nonlinear stability, circuit stability, or RF signoff.
Carry this boundary into any derivative note, paper draft, or slide.
No VNA or instrument control, upload parser, live solver, matching-network recommendation, device or vendor ranking, product claim, calibration service, or signoff action is active.
Carry this boundary into any derivative note, paper draft, or slide.
A real study needs owned bias- and temperature-tagged complex data, reference-plane and impedance definitions, calibration and de-embedding provenance, uncertainty propagation, broadband quality checks, compact-model provenance, and accountable RF review.
Carry this boundary into any derivative note, paper draft, or slide.
