Rogers AD300D 2-Layer 40mil Low-Loss PTFE PCB with EPIG Nickel-Free Finish

1.Introduction of Core

AD300D laminates are ceramic-filled, glass-reinforced PTFE-based materials designed to offer a controlled dielectric constant, low loss performance, and excellent passive intermodulation (PIM) performance. They are specifically engineered and manufactured to meet the demands of today's wireless antenna markets. This PTFE resin based material is compatible with standard PTFE fabrication and provides a cost-effective construction to improve electrical and mechanical performance.

2.Key Features

Dielectric Constant of DK 2.94 at 10GHz/23°C
Dissipation Factor of 0.0021 at 10GHz/23°C
Coefficient of Thermal Expansion: 24 ppm/°C (X-axis), 23 ppm/°C (Y-axis), and 98 ppm/°C (Z-axis) within -55 to 288°C
Thermal coefficient of dielectric constant: -73 ppm/°C
UL 94 V-0 flame retardant rating

3.Benefits

Low loss tangent (<0.002 at 10 GHz) for excellent circuit performance in all typical wireless frequency bands
Controlled dielectric constant (±0.05) for repeatable circuit performance
Very low PIM (-159 dBc at 30 mil, 1900 MHz) for excellent antenna performance and reduced yield loss due to PIM related issues
Excellent dimensional stability for repeatable circuit performance and improved manufacturing yields
Compatible with standard PTFE fabrication processes
Cost-effective construction with enhanced electrical and mechanical performance
