BLNKK's current understanding
Please check the details- Structure / observation location
- RF package transmission lines, transitions and ports
- Observation stage
- Passive-coupon or package S-parameter validation
- Phenomenon to localize
- Frequency-dependent insertion and return loss
- Engineering decision
- Use de-embedded ports and transition geometry to determine comparisons of materials, impedance or transition structures
- Sample evidence still required
- How can port order, calibration planes and frequency bands be traced for a single path?
Paths to assess first
Paths serve different purposes and can be combined01
Ports and fixture modelsReview measurement ports/calibration and the actual fixture model. Do not interpret DUT loss before these are confirmed.
First02
Actual transition-model preparationPrepare physical comparisons using actual transitions and material stacks, pending valid measurement observations.
First03
Paired-spectrum and measurement preparationPrepare repeated S21/S11 comparisons using the defined ports and frequency band, without claiming fixture effects have been removed.

Sample suitability still needs confirmationCheck VNA fixturing and port processingKeysight · Can help answer: The official manual lists fixture simulation, network de-embedding, port-direction and reference-impedance processing. First ask whether this model and measurement band are supported by the actual configuration.
→Review of ports and fixture modelsBLNKK engineering research summary · Can help answer: Review measurement ports/calibration and the actual fixture model. Do not interpret DUT loss before these are confirmed.
→Preparation for transition or spectral methodsBLNKK engineering research summary · Can help answer: Actual transition models and paired-spectrum measurements can be prepared independently. When one has complete inputs, begin its method design first.
