Rogers DiClad 880 0.508mm 0.762mm 1.524 mm PTFE Woven Fiberglass Copper Clad Laminate
DiClad 880 Laminate is a high-performance woven fiberglass/PTFE composite laminate designed for use as a printed circuit board substrate. It offers an excellent balance of electrical and mechanical properties, making it suitable for demanding high-frequency applications. The woven fiberglass reinforcement provides superior dimensional stability and uniform dielectric properties compared to non-woven reinforced PTFE laminates of similar dielectric constant.
With its controlled PTFE-to-fiberglass ratio, DiClad 880 substrate delivers consistent electrical performance across a wide frequency range, along with excellent chemical resistance and mechanical reliability. It is particularly well-suited for applications where low loss, signal integrity, and stable electrical characteristics are critical.
Key Features & Benefits:
1) Extremely Low Loss Tangent–Minimizes signal attenuation in high-frequency circuits.
2) Excellent Dimensional Stability–Maintains shape and alignment under thermal and mechanical stress.
3) High Uniformity of Dielectric Constant–Consistent electrical behavior across the substrate and over frequency.
4) Stable Dissipation Factor vs. Frequency–Ensures reliable performance in broadband and multi-band designs.
5) Strong Mechanical Performance–Good tensile and flexural strength for reliable assembly and use.
6) Superior Chemical Resistance–Withstands harsh processing and operating environments.
Typical Applications
Military Radar Feed Networks
Commercial Phased Array Antennas
Low-Loss Base Station Antennas
Missile Guidance Systems
Digital Radio Antennas
Filters, Couplers, and Low-Noise Amplifiers (LNAs)
