RO4830 High Frequency PCB

Introduction
Rogers' RO4830 high frequency laminates are thermoset materials that provide a dependable and cost-effective substitute for traditional PTFE based laminates.

RO4830 thermoset laminates are particularly suitable for millimeter wave applications that require cost-efficiency, such as automotive radar sensors operating in the 76-81 GHz frequency range. These laminates can be manufactured using standard FR-4 processes and are specifically designed for use as cap layers in FR-4 multi-layer board designs commonly employed in PCB applications for 76-81 GHz automotive radar sensors.



Features
RO4830 has a dielectric constant of 3.24, making it an excellent choice for high-frequency applications.

It exhibits an impressive insertion loss of just 2.2 dB/in for 5mil thickness and reduced to 1.8 dB/in for 9.4mil thickness at 77 GHz. This low insertion loss helps to maintain signal integrity even at high frequencies, resulting in reliable and accurate data transmission.

The laminates hold a UL 94 V-0 flame retardant rating and feature an optimized filler, resin, and glass composite system.

The laminates utilize reverse treated smooth LoPro® copper foil to improves signal quality and contributes to more efficient and consistent electrical performance.
