AD255A Laminate from Arlon
Arlon’s AD255A is a woven fiberglass reinforced PTFE composite material designed as a low-cost laminate with excellent low-loss characteristics. Features of AD255A include lower loss through the use of optimizing the trade-off between thicker and thinner glass styles, strategic use of lower loss ceramics at the exclusion of lossier glass, as well as a tighter DK tolerance. The AD255A design offers a higher degree of performance over comparable legacy PTFE/glass laminates that do not contain ceramic. This results in lower loss, higher antenna efficiencies, lower thermal expansion properties, and greater phase stability.
This material combines the excellent low-loss electrical properties of PTFE resin with the thermal properties of ceramic and the enhanced value of cost-effective fiberglass styles to provide low-cost laminate materials suitable for high-volume commercial wireless communication applications.
The electrical properties of AD255A are highly desired in applications where higher frequency and expectations for increased fidelity with broadband signals are beyond the performance capabilities offered by high-temperature or low-temperature ceramics and thermosets.
The stability of PTFE over a wide frequency range and its low loss properties make AD255A ideal for a variety of microwave and R/F applications in telecom infrastructure. The inclusion of micro-dispersed ceramic provides thermal stability to the laminate in the form of lower CTE values and greater Phase Stability across temperatures. The X and Y CTE matches the CTE of copper.
AD255A is compatible with the processing used for standard PTFE-based printed circuit board substrates. Its low Z-axis thermal expansion improves plated through-hole reliability compared to typical PTFE-based laminates. Low X-Y expansion improves BGA solder-joint reliability.

AD300A Laminate from Arlon
AD300A is a woven fiberglass reinforced PTFE/Microfine Ceramic composite material and is a significant improvement in cost/performance over traditional fluoropolymer-glass laminates. This combination offers designers an advantage for improving electrical performance through the use of advanced material without the additional cost traditionally associated with higher performance.
AD300A offers the Tightest Commercial Dielectric Constant Tolerance in the industry, 3.00 ±0.04. In comparison, competitive offerings are currently at 3.00 ±0.05. This tighter performance provides designers with a higher degree of impedance control, critical for maximum power transfer (S21) and for minimal insertion loss (S11). Combined with AD300A’s low loss properties, these properties lead to higher antenna gain.
AD300A was specifically developed for Base Station Antennas and Base Station Power Amplifiers where low loss and low PIM is critical. Other key performance attributes include low moisture absorption, low thermal coefficient of the dielectric (CTEr), high copper peel strength and good dimensional and thermal stability. The 3.00 Dielectric Constant also provides a small degree of miniaturization that is critical to the size constraints of some antenna designs.
