Rogers AD250C laminate and Custom High-Frequency double side PCB built on 0.508 mm (20mil) substrate with Pure gold Surface /No Blind vias /buried vias

Product Description

In today's rapidly evolving wireless communication landscape, the demand for high-performance antenna systems continues to grow. Rogers Corporation's AD Series™ antenna materials address these challenges head-on, with the AD250C™ laminate representing a particularly compelling solution for cost-sensitive applications requiring excellent RF performance.

AD250C is a glass-reinforced, PTFE-based laminate engineered specifically for wireless antenna markets. It combines a controlled dielectric constant with low-loss characteristics and outstanding passive intermodulation (PIM) performance. The woven glass reinforcement ensures good circuit processability, enabling high-yield circuit board fabrication. Available with standard electrodeposited (ED) or reverse-treated ED copper foil options, AD250C laminates help reduce circuit losses and optimize antenna PIM performance.

Material Advantages

Controlled Dielectric Performance:
AD250C delivers a tightly controlled dielectric constant of 2.50 ± 0.04 at 10 GHz, ensuring consistent impedance control and repeatable circuit performance across production batches. This precision is essential for maintaining antenna matching and minimizing return loss.

Low Loss Characteristics:
With a dissipation factor of just 0.0013 at 10 GHz, AD250C enables low insertion loss in transmission lines and feed networks. This translates to higher antenna efficiency and improved system gain.

Excellent PIM Performance:
The material achieves very low passive intermodulation values of -159 dBc to -163 dBc (measured on 30 mil and 60 mil laminates with reverse-treated ED copper), dramatically reducing the risk of PIM-related failures in sensitive receive paths.

Thermal and Mechanical Stability:

Coefficient of Thermal Expansion (CTE): X-axis (47 ppm/°C), Y-axis (29 ppm/°C), and Z-axis (196 ppm/°C) over the range of -55°C to 288°C

Decomposition temperature (Td) exceeds 500°C, providing a wide processing window

High Tg > 280°C supports lead-free soldering processes

Dimensional Stability:
The woven glass reinforcement and optimized resin system provide excellent dimensional stability (0.02/0.06 mils/inch after etch and bake), minimizing registration errors during multilayer lamination and improving manufacturing yields.

Moisture Resistance:
With moisture absorption of only 0.04%, AD250C maintains stable electrical properties even in humid environments, an essential attribute for outdoor antenna applications subject to weather exposure.
