DEVICE REPLAY LAB / SA-KNOW-RF-SPARAM-001

Move the reference plane before trusting the device.
Device / RF & High-Frequency

Complex S-parameters only become device evidence after the reference impedance, fixture, correction method, residual error, stability/passivity scope, noise model, and uncertainty chain are explicit. This packet keeps those layers visible in every row.

EVIDENCE SEQUENCE

What the learner should inspect first.

This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.

01

Read the real reference impedance and full complex intrinsic S matrix before reducing the network to gain or return-loss scalars.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
02

Cascade the passive left and right fixture boxes, then compare the fixture-embedded observation with lossless port extension, a symmetric split-fixture proxy, and exact declared-fixture inversion.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
03

Use fixture sigma-max as a pointwise passivity screen and K with Delta as an active linear two-port screen; neither is broadband causality or RF signoff.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
04

Keep first-order fT and fmax separate from measured or model-extracted performance, and carry gm, capacitance, resistance, bias, layout, and frequency-range assumptions with the result.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

05

Read the four-noise-parameter equation as source-termination literacy, then name the tuner, receiver, temperature, calibration, and uncertainty evidence absent from this synthetic packet.

METHODS

Precomputed model contract.

The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.

method

Deterministic 3 x 4 x 4 x 3 x 2 x 21 sweep over assumed small-signal device, passive fixture, correction class, residual-error state, real reference impedance, and logarithmic frequency.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

Original Y-to-S and S-to-ABCD equations with positive-delay passive fixture cascades; no copied Touchstone data, compact model, PDK, or external device value.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

Twelve official, primary, standards-metadata, academic, and open-source documentation anchors are mapped to five RF nodes without mirroring controlled or copyrighted source content.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

LIMITS

Useful, but deliberately bounded.

No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.

non-claim

The port-extension and symmetric split-fixture methods are teaching proxies, not VNA calibration, multiline TRL, IEEE 370 compliance, or production de-embedding software.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

No instrument control, upload parser, live EM/SPICE/compact-model solver, matching-network recommendation, device or vendor ranking, product claim, or RF signoff.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

Real RF evidence needs owned bias- and temperature-tagged complex data, exact port and impedance definitions, calibration/de-embedding provenance, propagated uncertainty, broadband quality checks, model lineage, and accountable review.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

SOURCE ANCHOR

Link-only public source spine.

SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
