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.
