A Versatile Alternative to PTFE Laminates
In the rapidly evolving world of electronics, the demand for high-performance, yet cost-effective solutions has never been greater. Addressing this need, we proudly present the RO4830 PCB – a cutting-edge printed circuit board that combines exceptional performance with unparalleled affordability. At the heart of this innovative PCB is the Rogers RO4830 high-frequency laminate, a thermoset material that serves as a reliable alternative to conventional PTFE-based laminates. With a slightly higher dielectric constant of 3.2 at 77GHz, the RO4830 laminate offers a unique balance of electrical properties and cost-effectiveness, making it an ideal choice for price-sensitive millimeter wave applications.
Unparalleled High-Frequency Performance
One of the key features that sets the RO4830 PCB apart is its exceptional insertion loss of just 2.2 db per inch at 77GHz. This remarkable performance is achieved through the use of LoPro reverse treated copper foil cladding, which contributes to the laminate's excellent high-frequency characteristics. Designed for demanding millimeter wave applications, the RO4830 PCB is well-suited for use in 76-81 GHz automotive radar sensors.
