Statement of Work & Project Statement


Background

Next-generation 5G communications solutions require ultra-low loss laminate materials and PCBs/substrates for efficient design and manufacturing. However, these materials pose challenges. For example, there is no consistent methodology for measuring transmission loss or Df/Dk, especially for higher frequencies (e.g., >30 GHz). Many different approaches are currently used, requiring different fixtures and test methods, sample preparation, and/or data analysis/extraction. 


Project Focus

The goal of this project is to develop a guideline/best practice for a standardized measurement  and test methodology that can be shared with industry and relevant standards organizations. Initial focus will be to benchmark current available test methods and provide pro/con analysis, identify gaps (if any) for extending test methods to 5G/mmWave frequencies, as well as develop reliable reference standard materials for set-up and calibration.

The project will have two distinct phases:

  • Phase 1: Develop technical guidelines and generate best practices for characterization of ultra-low loss laminate materials in the range of 5-100 GHz
  • Phase 2: Extend the guidelines to PCB/substrate level characterization
