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 less than or equal to 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, multi-layer RF PCBs
temperature stable antennas and other microwave and RF applications.
