Rogesr PCB RT/duroid 5880(Rogers 5880) material specification

Rogers RT/Duroid 5880 high frequency PCB is made of PTFE glass fiber reinforced material. High frequency circuit design always has strict requirements for the dielectric constant of printed circuit board. The dielectric constant of RT / Duroid 5880 measured at 10 GHz working frequency is only 2.2, which is obviously lower than that of similar materials on the market at present. Therefore, from the perspective of performance parameters and production cost, the board is more suitable for high-frequency design and application than similar products. At the same time, the dielectric loss of the plate measured under the same standard is only 0.0009. The extremely low dielectric loss makes it very suitable for high frequency and wide band design applications requiring minimum dispersion and loss, It is mainly used in high frequency circuit board of point-to-point digital radio antenna, microstrip and stripline circuit, millimeter wave application, missile guidance system, military radar system and commercial aviation telephone.

The characteristics of RT / Duroid 5880 high frequency board are as follows

1. Very low dielectric constant, measured at 10 GHz, the dielectric constant is 2.20 ± 0.02;

2. Very low dielectric loss, measured at 10 GHz, the dielectric loss factor is 0.0009;

Rogers RT/duroid 5880 (Rogers 5880) material
Rogers RT/duroid 5880 high frequency laminates are PTFE composites reinforced with glass microfibers.

RT/duroid 5880 laminates has a low dielectric constant (Dk) and low dielectric loss, making them well suited for high frequency/broadband applications. Helping to maintain the Dk uniformity are the randomly oriented microfibers reinforcing the PTFE composites.
