1. Introduction of RT/duroid 5880
Rogers RT/duroid 5880 high - frequency laminates are crafted as PTFE composites strengthened by glass microfibers. Engineered specifically for the most demanding stripline and microstrip circuit applications, these laminates offer a distinct advantage. Thanks to the randomly arranged microfibers, they achieve an outstanding level of dielectric constant uniformity.

|
|
Not only is the dielectric constant of RT/duroid 5880 laminates consistent from one panel to another, but it also remains stable across a broad frequency spectrum. Moreover, its impressively low dissipation factor expands the applicability of RT/duroid 5880 laminates well into the Ku - band and even higher frequency ranges. This makes it an ideal choice for high - performance, frequency - sensitive electronic projects. |
