Bear, DE – Arlon Inc. announced the availability of the CLTE-XT
Microwave Laminate. CLTE-XT represents the eXtended Technology of the
existing CLTE product line. CLTE-XT has both “Best-in-Class” Insertion
Loss (S21) and Loss Tangent (0.0012 at 10GHz).
CLTE-XT is a micro dispersed ceramic PTFE composite utilizing a woven
fiberglass reinforcement to provide the highest degree of dimensional
stability, critical in multi-layer designs. CLTE-XT is in a “League of
its Own” when utilizing thin (i.e. 0.005” and 0.010”) substrates or when
CLTE-XT is combined with thin film resistor-conductor materials such as
Ohmega-Ply® and TCR® foils utilized for embedded resistors in
applications that require a high degree of resistor consistency.
During Development, Arlon focused not only reducing Loss Tangent, but,
also in reducing Conductive Losses. As a result, CLTE-XT Insertion Loss
is clearly “Best-In-Class”. CLTE-XT has very low CTExyz and the Lowest
TCEr (dielectric constant stability across temperature) for applications
that require Electrical Phase Stability, Dielectric Constant Stability,
and Mechanical Stability well over a -55 to 150°C Operating Temperature.
The X-Y axis thermal expansion closely matches ceramic chip carriers and
the Z-axis thermal expansion closely matches copper for ultimate thermal
cycling reliability.
CLTE-XT continues the competitive advantages of CLTE (dimensional
stability, low absorption of moisture and processing chemicals, ease of
processability, registration consistency). The higher thermal
conductivity of CLTE-XT improves heat transfer relative to alternative
materials and enables better power handling.
Applications include Avionics, Military and Space Electronics who
require a higher degree of performance such as Phase Sensitive Arrays,
Radar Manifolds, RF/Microwave Communications, CNI (Communication
Navigation and Identification), EW and SIGINT applications. CLTE-XT
would also have value for sensitive filter applications.
