Accurate S-Parameter Measurements for PCB Channel Block Characterization
Join our Southern MN section in person back at Mann Hall to view Part III of the 2ND Annual IEEE Region 4 Midwest PCB Fest!
The speaker for this talk will be remote (sponsored by IEEE Region 4), and pizza will be served to attendees at the end of the talk.
The original description of the seminar from Region 4's posting is below:
Title: Accurate S-Parameter Measurements for PCB Channel Block Characterization
Abstract: Extracting high-quality S-parameters for a DUT from measurements inherently involves de-embedding them from a total structure that includes test fixture lead-ins. These lead-ins typically include probes or connectors, and potentially some length of non-coaxial transmission-line, e.g., stripline or microstrip on a PCB, as well as via transitions, in addition to the DUT. A common current de-embedding approach often used for DUTs on printed circuit boards, packages, and cabling for example, utilizes a 2X Thru, or 1X Open, together with the total structure to extract the DUT S-parameters. For many current high-speed and high-frequency applications it is necessary to do 3D full-wave electromagnetic simulation in order to develop a high-quality test fixture from which successful de-embedding can result. The features that comprise good lead-in test fixturing from which DUT S-parameters can be extracted will be detailed in this presentation. EM simulation for developing test fixtures will be discussed and examples provided. This presentation will also discuss making quality S-parameter measurements with a VNA, and provide comparison results. Examples to 50 GHz will be presented.
