Rogers DiClad 870 Microwave PCB - 31mil 93mil 125mil Woven Fiberglass Reinforced PTFE-Based Circuit Boards
(Printed Circuit Boards are custom-made products; the images and parameters shown are for reference only.)
General Description
The Rogers DiClad 870 Microwave PCB is a high-performance circuit board designed for RF and microwave applications. Built on Rogers DiClad 870 laminates, this PCB features woven fiberglass/PTFE composites that provide excellent dimensional stability and low dielectric constant (Dk 2.33 at 10 GHz and 1 MHz). With a low dissipation factor of 0.0013 at 10 GHz, the DiClad 870 PCB ensures minimal signal loss, making it ideal for high-frequency systems. Available in 31mil, 93mil, and 125mil thicknesses, it is suitable for a wide range of applications, including phased arrays, radar systems, and base station antennas.
