What circuit boards do we do? (34) AD255C High Frequency PCB

Introduction

Rogers AD255C laminates are a sophisticated blend of a fluoropolymer resin system, carefully selected ceramic elements, and fiberglass reinforcement. By leveraging the exceptional thermal properties of fluoropolymer resin, alongside the strategic integration of ceramic materials and fiberglass reinforcement, AD255C materials stand out for their reduced loss, lower thermal expansion characteristics, and minimized passive intermodulation (PIM) effects. This unique combination results in a specialized RF laminate material that excels in a variety of microwave and RF applications within telecommunication infrastructure.

Features

The AD255C boasts several remarkable features, including:

Very Low Loss PTFE and Ceramic Filled Composite: This advanced composite merges PTFE with ceramic fillers, resulting in exceptionally low signal loss, making it perfect for high-frequency applications.

Exceptional Loss Tangent: With a loss tangent of only 0.0014 at 10 GHz and base station frequencies, this material guarantees efficient signal transmission, minimizing energy waste and enhancing overall performance.

Dielectric Constant of 2.55: The material features a dielectric constant of 2.55, providing reliable electrical insulation with tight tolerances, which is vital for maintaining signal integrity in sensitive applications.

Low Profile Copper: The inclusion of low profile copper enhances conductivity while preserving a compact design, making it ideal for space-constrained environments.

Low Z-Direction CTE: With a coefficient of thermal expansion (CTE) of 50 ppm/°C in the Z-direction, this material offers excellent dimensional stability across temperature variations, ensuring consistent performance under a wide range of operating conditions.
