AD255C PCB Material High Frequency Laminates Copper Clad Sheet

AD255C is a glass-reinforced, PTFE-based composite engineered to deliver a stable dielectric constant, low signal loss, and excellent passive intermodulation (PIM) performance. The woven glass construction enhances circuit processability and supports high-yield PCB fabrication.

AD255C meets the diverse requirements of modern antenna designs. This versatility, combined with precise dielectric control, ensures consistent impedance performance across production runs.

The material is offered with standard electrodeposited (ED) copper or reverse-treated ED copper foil, allowing designers to optimize for reduced circuit loss and improved PIM performance.

As a PTFE-based composite, AD255C exhibits exceptionally low loss—typically below 0.002 at 10 GHz—along with minimal moisture absorption (<0.1%) and high copper peel strength (>10 pli). These characteristics make AD Series laminates a reliable, high-performance solution for antenna applications.

Features and Benefits

1. Low loss tangent (<0.002 at 10 GHz) – Delivers excellent circuit performance across all common wireless frequency bands
2. Controlled dielectric constant (±0.05) – Ensures repeatable and reliable circuit performance
3. Very low PIM (-159 dBc at 30 mil, 1900 MHz) – Enhances antenna performance and minimizes yield loss due to PIM issues
4. Excellent dimensional stability – Supports consistent circuit performance and improved manufacturing yields

Typical Applications

1. Cellular infrastructure base station antennas
2. Automotive telematics antenna systems
3. Commercial satellite radio antennas
