What is The Difference Between Rogers 3003 and 3003G2?

Hits : 6

Rogers Corporation's RO3003 and RO3003G2 are both high-frequency circuit materials, PTFE (polytetrafluoroethylene) composite materials, mainly used in commercial microwave and radio frequency (RF) applications. Although both materials belong to the RO3000 series, they have some differences in design, properties and applications:

Main features of RO3003:

Dielectric constant: 3.00 at 10GHz.

Loss coefficient: 0.0013 at 10GHz.

Application: 

Suitable for automotive radar, global positioning satellite antenna, mobile communication system, patch antenna, direct transmission satellite, data link cable system, remote meter reading device, etc.

Stability: 

Excellent dielectric constant stability over the entire temperature range, eliminating the dielectric constant changes that occur when using PTFE glass materials at room temperature.

Main Features of RO3003G2:

Dielectric Constant: 

3.00 at 10GHz, 3.07 at 77GHz.

Loss: Insertion loss is 1.3dB/inch at 77GHz (for 5 mil thick material).

Design Optimization: 

Based on customer feedback in the industry, it is specially designed for next-generation millimeter wave automotive radar applications, optimizing the resin and filler systems to provide lower insertion loss.

Copper Foil: 

Using new extremely low roughness electrolytic copper foil (VLP ED) to help reduce insertion loss.

Application: Especially suitable for advanced driver assistance systems (ADAS) such as adaptive cruise control, forward collision warning systems, active braking or lane change assist systems.

Main Differences:

Dielectric Constant: 

The dielectric constant of RO3003G2 at 77GHz is 3.07, which is slightly higher than the 3.00 of RO3003 at 10GHz, indicating that RO3003G2 maintains a lower dielectric constant at higher frequencies.

Loss Performance: 

RO3003G2 has lower insertion loss at 77GHz, which makes it more ideal in high-frequency applications such as high-performance automotive radar.

Material Optimization: 

RO3003G2’s resin and filler system have been further optimized to meet the needs of millimeter wave automotive radar applications.

Copper Foil Technology: 

RO3003G2 uses a new type of extremely low roughness electrolytic copper foil, which helps reduce insertion loss and improve circuit performance.

Application Focus: 

The RO3003G2 is designed for next-generation millimeter wave automotive radar applications, while the RO3003 is suitable for a wider range of commercial microwave and RF applications.

Filling System: 

RO3003G2 may use more advanced filling technology, which helps improve the overall performance of the material, especially at high frequencies.

Structural Uniformity: 

RO3003G2 may be more uniform in material and structure, which helps reduce media porosity, thereby improving circuit consistency and reliability.

Microvia Design: 

RO3003G2 may support higher density and smaller diameter microvia design, which is beneficial for achieving more compact and complex circuit layouts.

Thickness Options: 

RO3003G2 may offer multiple media thickness options, which provides designers with more flexibility in different applications.

Size Options: 

The RO3003G2 may be available in a variety of standard size options, including larger panel sizes, which helps reduce material waste during manufacturing.

Environmental and Safety Data: 

RO3003G2 may have more detailed environmental and safety data sheets (such as MSDS or PSIS), which are critical for safety when handling and using the material.

Processing Guide: 

RO3003G2 may come with more detailed processing guides to help manufacturers optimize the processing process and improve yield and performance.

Market Positioning: 

RO3003G2 may be more focused on the high-end market, especially those applications with extremely high performance requirements, while RO3003 may be more suitable for a wide range of commercial applications.

Cost Considerations: 

Although RO3003G2 provides higher performance, its cost may be correspondingly higher, which may affect the choice of some cost-sensitive applications.

Technical Support and Resources: 

RO3003G2 may provide additional technical support resources such as technical articles, white papers, calculators and tools to help designers and manufacturers make better use of this material.

Choosing RO3003 or RO3003G2 will ultimately depend on specific application needs, performance requirements, cost budget, and design flexibility. Designers should select the most appropriate materials based on the specific parameters and goals of the project.
