Introduction to RT/duroid 5880
The RT/duroid 5880 is a high-frequency laminate that combines PTFE with glass microfibers. This composite material is engineered for precise stripline and microstrip circuit applications, offering unparalleled dielectric constant uniformity across different panels. The randomly oriented microfibers contribute to this uniformity, ensuring consistent performance across a wide frequency range. With a low dissipation factor, RT/duroid 5880 is particularly effective for applications extending into the Ku-band and beyond, making it an essential component in modern electronic designs.
Key Features
The RT/duroid 5880 PCB is characterized by several notable features:
Dielectric Constant: A consistent value of 2.2, with a tight tolerance of 0.02 at 10 GHz / 23°C, ensures reliable signal propagation.
Dissipation Factor: An exceptionally low dissipation factor of 0.0009 at 10 GHz minimizes energy loss, enhancing the efficiency of high-frequency circuits.
Temperature Coefficient of Dielectric Constant (TCDk): With a TCDk of -125 ppm/°C, the PCB maintains stable performance across a range of temperatures.
Moisture Absorption: A low moisture absorption rate of just 0.02% makes this PCB ideal for high-moisture environments, preventing degradation over time.
Isotropic Properties: The PCB exhibits isotropic behavior, with a coefficient of thermal expansion (CTE) of 31 ppm/°C along the X-axis, 48 ppm/°C along the Y-axis, and 237 ppm/°C along the Z-axis.
