This laminate is ideal for applications requiring precision, reliability, and high-frequency performance, such as automotive radar systems, satellite antennas, and wireless communication modules.

Key Material Specifications

Introduction to Rogers RO3203

Rogers RO3203 is a ceramic-filled PTFE laminate, enhanced with woven fiberglass reinforcement, which provides dimensional stability and mechanical rigidity. It belongs to the RO3000 series, offering improved mechanical stability over other materials in the series. With a dielectric constant (Dk) of 3.02 ± 0.04 and a dissipation factor (Df) of 0.0016 at 10GHz, this laminate is optimized for low-loss, high-frequency circuits that require consistency and reliability.

Why Rogers RO3203 Stands Out

• Low Dielectric Loss: Ensures minimal signal degradation, enabling efficient operation at frequencies exceeding 40GHz.
• Mechanical Stability: Woven glass reinforcement provides dimensional stability during manufacturing and operation.
• Cost-Effective: Offers a competitive price point compared to other high-performance laminates, making it ideal for volume production.
• Thermal Reliability: Can withstand extreme heat with a high decomposition temperature (Td > 500°C).
