Why RO3003 — Dk 3.00 ± 0.04 and Df 0.0010 at 10 GHz — is the industry-standard laminate for 77/79 GHz automotive radar and 5G millimeter-wave infrastructure.
Rogers RO3003 is a high-frequency circuit board laminate specifically designed for millimeter-wave applications. It is constructed from ceramic-filled PTFE (polytetrafluoroethylene) material, with its core advantage lying in its ability to provide exceptionally stable and outstanding electrical performance under extremely high frequencies and temperature variations.
Leveraging the aforementioned characteristics, RO3003 is particularly suitable for demanding high-frequency application scenarios. It serves as the industry-standard material for 77/79 GHz automotive radar sensors (used in ADAS functions such as adaptive cruise control and collision warning). Furthermore, it is widely used in 5G wireless communication millimeter-wave infrastructure (e.g., base station antennas), satellite communication, and high-end radio frequency systems requiring high stability, such as filters and oscillators.
To meet the higher performance requirements of next-generation millimeter-wave applications (especially advanced autonomous driving), Rogers developed an enhanced version based on RO3003 — RO3003G2. By employing ultra-low profile copper foil and an optimized filler system, it further reduces insertion loss and achieves a more consistent dielectric constant, enabling longer detection ranges and higher design precision.
The Rogers RO3003 series of high-frequency circuit boards provides an excellent solution that balances performance, reliability, and cost for millimeter-wave circuit design. It is a key material driving the development of modern RF technology, particularly in automotive radar and 5G communication.
Common questions about Rogers RO3003 laminates.
RO3003 is specified at Dk 3.00 ± 0.04, and the value stays stable across temperature and frequency changes. It also avoids the dielectric performance step that ordinary PTFE materials show near room temperature, which greatly simplifies design.
Its Df of only 0.0010 at 10 GHz preserves signal integrity at 77/79 GHz — the bands used by ADAS functions such as adaptive cruise control and collision warning. Long-term PTH reliability under thermal cycling further suits automotive environments.
RO3003G2 adds ultra-low profile copper foil and an optimized filler system, further reducing insertion loss and tightening dielectric constant consistency — enabling longer radar detection range and higher design precision for advanced autonomous driving.
Yes. It is compatible with standard high-frequency PTFE circuit board processing, which helps control mass-production costs and shortens time-to-market — a key reason it is so widely adopted.
