AD320A Laminate from Arlon

AD320A is a woven fiberglass reinforced PTFE/Microfine Ceramic composite material and is a significant improvement in cost/performance over traditional fluoropolymer-glass laminates that do not use ceramics. 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.

AD320A 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 (CTεr), high copper peel strength and good dimensional and thermal stability. The 3.20 Dielectric Constant also provides a small degree of miniaturization that is critical to the size constraints of some antenna designs.

AD320A is compatible with the processing used for standard PTFE based printed circuit board substrates. In addition, the low Z-axis thermal expansion provided by the ceramic loading, will improve plated through hole reliability compared to typical PTFE based laminates.
