RF-10 PCB 2-Layer 125mil High Dielectric Constant Laminates for Microstrip Patch Antennas
1.Overview of RF-10
RF-10 copper clad laminates are advanced composites made from ceramic-filled PTFE and woven fiberglass. They offer high dielectric constant and low dissipation factor, making them suitable for high-frequency applications. The thin fiberglass reinforcement enhances both rigidity and dimensional stability, which is essential for multilayer circuit manufacturing.
These laminates are designed to be a cost-effective substrate with reliable delivery times. RF-10 addresses the demand for size reduction in RF applications. It adheres well to smooth, low-profile copper, optimizing insertion losses at higher frequencies where skin effect losses become significant.
