Introducing our latest shipment PCB based on the advanced AD250 material, specifically designed for commercial microwave and RF applications. The AD250C laminate offers a tightly controlled dielectric constant of 2.50, ensuring superior performance and reliability in today's telecommunications infrastructure.

Key Features:
Rogers AD250C Woven Glass Reinforced PTFE Antenna Grade Laminates provide the foundation for this PCB. With a dielectric constant of 2.5 and tight tolerance at 10 GHz/23°C, this material delivers precise electrical characteristics. The PCB exhibits a low loss tangent of 0.0013 at 10GHz and base station frequencies, ensuring excellent circuit performance. Its decomposition temperature (Td) exceeds 500°C, making it highly durable in high-temperature environments. Additionally, the AD250C laminate boasts an extremely low moisture absorption rate of 0.04% and exhibits excellent dimensional stability with a coefficient of thermal expansion (CTE) of 47 ppm/°C (X-axis), 29 ppm/°C (Y-axis), and 196 ppm/°C (Z-axis).

Benefits:
The low loss tangent (<0.002 at 10 GHz) of this PCB enables superior circuit performance across a wide range of wireless frequency bands. With a controlled dielectric constant (±0.05), the PCB ensures consistent and predictable circuit performance. The ceramic material used in the AD250 laminate provides exceptional stability of the dielectric constant during temperature changes. The very low Passive Intermodulation (PIM) of -159 dBc at 30 mil, 1900 MHz significantly reduces signal interference, resulting in improved antenna performance. The excellent dimensional stability of the PCB enhances repeatability of circuit performance and contributes to high manufacturing yields. Compared to typical PTFE-based laminates, this PCB offers improved reliability and performance.
