Ultra-low-loss PTFE laminate for microwave & mmWave
Rogers RO3003 is a ceramic-filled PTFE composite engineered for the most demanding high-frequency circuits — 77 GHz automotive radar, 5G mmWave, and satellite communications. With Dk 3.00 ± 0.04 and an exceptionally low Df of 0.0010, it delivers the stable, repeatable impedance control that microwave designs require.

Why RO3003
Features of Rogers RO3003 PCB
Engineered for heavy-industry RF environments where ordinary PCBs fall short.
Df 0.0010 at 10 GHz — the lowest loss in the RO3000 series, ideal for microwave & mmWave.
3.00 ± 0.04 enables tight, repeatable impedance control across bands.
The reference material for automotive radar and ADAS sensor front-ends.
0.04% uptake keeps Dk rock-stable from lab to harsh field use.
24 ppm/°C in z keeps plated through-holes reliable over thermal cycles.
Best price/performance among PTFE laminates for volume mmWave programs.

Frequently Asked Questions
1.What is RO3003 typically used for?
77 GHz automotive radar, 5G mmWave base stations, satellite communications, point-to-point microwave backhaul, LNBs and high-gain RF power amplifiers — anywhere ultra-low loss matters.
2.Can RO3003 be processed like FR-4?
No. It is a PTFE-based laminate and needs a dedicated PTFE process (special desmear, sodium etch, controlled lamination). Andwin runs a separate PTFE line, so your RO3003 boards are never mixed with standard epoxy jobs.
3. What is the dielectric constant tolerance?
3.00 ± 0.04 at 10 GHz (z-axis), stable across temperature and frequency — exactly what tight impedance control needs.
4.What lead time and minimum order?
RO3003 raw material is in stock. Prototypes typically ship in 7–10 days; volume MOQ is flexible — ask for a quote.
5. Can you build hybrid RO3003 + FR-4 stacks?
Yes. We routinely fabricate mixed-dielectric stack-ups (RO3003 with RO4350B or FR-4 cores) with simulated, verified impedance.
