Microwave circuit designers have many powerful tools. However most are strongly dependent on the accuracy of the input data. High frequency printed circuit board (PCB) material properties are often assumed to be very simple, but understanding the details can increase model accuracy and minimize design time.
Those familiar with high frequency behavior of circuit materials realize the term for relative permittivity of “dielectric constant” is a misnomer and is not a constant. The dielectric constant of any PCB material will vary with frequency. Additionally wave propagation properties can be altered by a relationship of substrate thickness to copper surface roughness and this can vary the dielectric constant as perceived by circuit performance, even when using homogenous material.This webinar will give a simple overview of common test methods used to determine the dielectric constant for high frequency materials, followed by a description of methods that are best for characterizing material properties for microwave modeling and design.Agenda:

  • Description of Common Test Methods
  • Optimal Test Procedures for Circuit Characterization
  • Real World Application of RF Circuit Design Best Practices

Why join this webcast?
The actual circuit defined dielectric constant is an elusive property for designers to properly incorporate into their design models. This webinar will help designers define the dielectric constant parameters of a circuit as related to frequency, circuit thickness and copper surface roughness.
