Bear, DE (May 8, 2008) – Arlon Inc. announced the availability of CLTE-AT,
the latest addition to the CLTE product line. CLTE-AT represents Arlon's
commercial offering using common technologies developed for the high
performance CLTE-XT, but modified to make the product more affordable
for commercial applications. To maintain its lower cost base, CLTE-AT
has fewer options for copper style and panel sizes.
CLTE-AT is a micro dispersed ceramic PTFE composite utilizing a very
fine woven fiberglass reinforcement to provide the highest degree of
dimensional stability and registration consistency, especially when
utilizing thin laminates such as 0.005” and 0.010”. CLTE-AT has
“Best-in-Class” Insertion Loss (S21) and Loss Tangent (0.0013) in the
commercial marketplace. To further improve performance in high-frequency
applications, CLTE-AT uses smoother copper styles with average surface
roughness (Rz) of <4.0µm, compared to many competitive offerings
using rougher 9-10 µm copper. This reduces insertion loss and
transmission line resistance while still maintaining peel strength
required for thin traces on thin laminates. For newer commercial
millimeter wave applications, this represents a significant performance
enhancement over existing technologies as skin effect losses become
significant at higher frequencies.
CLTE-AT has Low CTExyz (thermal expansion) and extremely low TCEr
(dielectric constant change with temperature). The low negative valued
TCEr and low positive CTExy nearly offset each other to provide a very
stable phase length and impedance values, even across wide temperatures.
The higher thermal conductivity of CLTE-AT also improves heat transfer
relative to alternative materials and enables better power handling.
Applications include temperature and loss sensitive filter applications,
collision avoidance radar, adaptive cruise control, temperature stable
antennas and other microwave and RF applications.
