IEEE 370-2020 pdf free.IEEE Standard for Electrical Characterization of Printed Circuit Board and Related Interconnects at Frequencies up to 50 GHz.
The purpose of this standard is to define methodologies by which high-quality scattering parameters (S-parameters) can be obtained for electrical interconnects that are intended to operate at microwave frequencies (up to 50 Gll). The standard includes requirements for designing test lixtures. evaluating measured data, removing test fixture and instrumentation elTects, and verifying the quality of the S-parameters. The primary focus of this standard development is measured S-parameters. However, the methodology is applicable to simulated S-parameters as well.
Note that this standard defines a set of metrics o be calculated and reported to the recipient of the S-parameter data. In order to comply with this standard, the values of the metrics shall be included in S-parameter data tile. However, the determination of passifail status of the results is out of the scope of this
standard, and is left to the recipient of the data.
Although the highest frequency of interest is set at 50 GHz in this document, the methodology is generally applicable to higher frequencies. The methods and techniques contained herein have been validated only to 50 GHz as of this writing.
The word chat! indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shall equals is required to).
The word should indicates that among seseral possibilities one is recommended as particularly suitable. without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required (should equals is reconunended that).
The word nsav is used to indicate a course of action permissible within the limits of the standard (nwi equals is permitted to).
The word con is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to).
The following referenced documents arc indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated rcfcrcnccs. the latest edition of the referenced document (including any amendments or corrigenda) applies.
