RO3003 Dk and Df
Rogers RO3003: design Dk 3.0 and Df 0.001 at 10 GHz (Ceramic-filled PTFE, design Dk). In the pcbplanner material library it is listed under rf laminate materials.
Datasheet values
| Entry | Dk | Df | at | Tg | Construction and test method |
|---|---|---|---|---|---|
| RO3003 | 3.0 | 0.001 | 10 GHz | — | Ceramic-filled PTFE, design Dk. |
Dk and Df depend on the glass style, the resin content and the test method, so the same product has different values in different constructions. Compare materials at the same frequency and, where possible, with the same method; for a construction not listed here, use the manufacturer’s construction table.
Dk and Df from 1 to 20 GHz
The datasheet gives one frequency. The table extends that point with the Djordjevic–Sarkar wideband Debye model, the same model the impedance and trace-loss calculators use: it keeps Df nearly flat and lets Dk fall slowly with frequency. These are model values, not measurements.
| Entry | 1 GHz | 2 GHz | 5 GHz | 10 GHz | 20 GHz |
|---|---|---|---|---|---|
| RO3003 | 3.00 / 0.0010 | 3.00 / 0.0010 | 3.00 / 0.0010 | 3.00 / 0.0010 | 3.00 / 0.00096 |
Each cell is Dk / Df.
