Test Channel Loss Characteristics
The test channel was fabricated with Polyclad PCL-FR-370-Laminate/PCL-FRP-370 Prepreg materials (Dielectric
constant of 3.7 and Loss Tangent of 0.02). The edge coupled differential striplines have the following geometries:
Trace Width (W) = 5 mils, Gap (S) = 5 mils, Height (B) = 16 mils.
