4-Layer, 1.6mm-Thick-RO3003-PCB: Advanced-Ceramic-PTFE-Composite-for-5G-mmWave-and-Automotive-Radar-from-Bicheng

Shipped: 7th-FEB-2025

1. Introduction of RO3003

Rogers RO3003 high-frequency laminates are advanced ceramic-filled PTFE composites engineered for superior performance in commercial microwave and RF applications. With exceptional stability of the dielectric constant (Dk) across a wide range of temperatures and frequencies, RO3003 eliminates the step change in Dk commonly seen near room temperature with traditional PTFE glass materials. This breakthrough ensures consistent, reliable performance in cutting-edge applications such as 77 GHz automotive radar, advanced driver assistance systems (ADAS), and 5G wireless infrastructure (mmWave). RO3003 is the ultimate choice for high-frequency designs demanding precision, stability, and innovation.

3. Benefits

Low Dielectric Loss for High-Frequency Performance

RO3003 laminates feature ultra-low dielectric loss, making them ideal for high-frequency applications up to 77 GHz, such as automotive radar and 5G mmWave systems.

 

Exceptional Mechanical Stability Across Temperatures

With outstanding mechanical properties that remain consistent across varying temperatures, RO3003 ensures reliable performance in stripline and multi-layer board constructions.

 

Uniform Mechanical Properties for Versatile Designs

RO3003 offers uniform mechanical properties across a range of dielectric constants, making it perfect for multi-layer board designs and hybrid constructions with epoxy glass materials.

 

Stable Dielectric Constant for Precision Applications

The dielectric constant of RO3003 remains stable across temperature and frequency variations, making it an excellent choice for band-pass filters, microstrip patch antennas, and voltage-controlled oscillators.

 

Low In-Plane Expansion Coefficient for Enhanced Reliability

RO3003’s low in-plane expansion coefficient matches that of copper, ensuring reliable surface-mounted assemblies and excellent dimensional stability, even in temperature-sensitive applications.

 

Cost-Effective Volume Manufacturing

RO3003 is produced using a high-volume manufacturing process, delivering exceptional performance at an economical price point, making it a cost-effective solution for high-frequency applications. RO3003 combines cutting-edge performance, reliability, and affordability, making it the go-to choice for advanced RF and microwave designs.
