Responsibilities
3D EM Simulation & Modeling
Full-Wave Modeling: Assist in creating high-fidelity 3D models of connectors and cable terminations using Ansys HFSS or CST Studio Suite
Virtual Prototyping: Run simulations to extract S-parameters and identify impedance discontinuities within the connector pin-field and mating interface
Optimization: Perform "what-if" analyses on mechanical variables (e.g., pin geometry, plastic dielectric constants, shield spacing) to optimize return loss and crosstalk
Lab Validation & Characterization
High-Frequency Measurement: Use Vector Network Analyzers (VNA) and Time Domain Reflectometers (TDR) to characterize physical prototypes up to 20 GHz or higher
Fixture De-embedding: Learn and apply de-embedding techniques (like AFR or TRL) to remove the effects of test boards, isolating the performance of the connector itself
Correlation: Compare lab measurement data against simulation models to validate accuracy and refine simulation methodologies
Crosstalk Simulation & Discovery (Pre-Silicon/Pre-Layout)
Aggressor-Victim Analysis: Use Ansys HFSS to perform "discovery" simulations identifying the most significant crosstalk contributors within a high-density pin array
NEXT/FEXT Modeling: Extract Near-End Crosstalk (NEXT) and Far-End Crosstalk (FEXT) S-parameters to determine the isolation levels between differential pairs
ICN Calculation: Calculate Integrated Crosstalk Noise (ICN) and Power Sum Crosstalk to evaluate total noise interference against IEEE 802.3 or OIF-CEI limit lines
Pin-Map Optimization: Based on crosstalk discovery, provide recommendations for optimized signal-to-ground ratios and pin-mapping (e.g., G-S-S-G patterns) to shield sensitive high-speed lines
Crosstalk Validation (Lab/Post-Layout)
Multi-Port Measurements: Utilize 4-port or 8-port Vector Network Analyzers (VNAs) to measure real-world crosstalk in physical prototypes and connector mating interfaces
Time Domain Analysis: Use TDR/TDT to locate the exact physical location of a crosstalk "hotspot" within a connector body or cable transition
Correlation: Document discrepancies between simulated crosstalk and measured crosstalk, investigating factors such as manufacturing tolerances in pin-to-pin spacing or plating consistency
Data Analysis & Automation
Scripting: Utilize Python or MATLAB to automate the processing of large Touchstone sNp file datasets
Compliance Testing: Analyze simulation and test results against industry standards such as IEEE 802.3 (Ethernet), USB4, or USCAR-2 specifications
Documentation & Collaboration
Technical Reports: Prepare professional SI reports summarizing performance vs. specifications for internal design reviews
Cross-Functional Support: Interface with Mechanical Engineers to explain how physical design changes impact electrical performance
