CLTE-XT represents the eXtended Technology of the existing CLTE product line. 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 resistorconductor materials such as Ohmega-Ply and TCRâ foils utilized for embedded resistors.

CLTE-XT has "Best-in-Class" Insertion Loss (S21) and Loss Tangent (0.0012). During Development, Arlon focused not only reducing Loss Tangent, but, also in reducing Conductive Losses. As a result, CLTE-XT Insertion Loss is "Best-In-Class".

The impact of copper foil roughness on conductor loss is due to increase in transmission line resistance as a result of skin effect. Arlon's CLTE-XT was designed to provide a quality peel strength without having to resort to the utilization of the lossier, rougher coppers prevalent in competitive products to achieve acceptable copper adhesion.

CLTE-XT has Low CTExyz and Very Low TCEr for applications that require Electrical Phase Stability, DK Stability, and Mechanical Stability well over a -55 to 150°C Operating Temperature. CLTE-XT continues the competitive advantages of CLTE (dimensional stability, low absorption of moisture and processing chemicals, ease of processability). The higher thermal conductivity of CLTE-XT improves heat transfer relative to alternative materials and enables better power handling.

Applications include Space and Military Electronics who require a higher degree of performance such as Phase Sensitive Arrays for Radar, RF/Microwave Communications, Aircraft Collision Avoidance Systems, JTRS, etc. CLTE-XT is also a preferred material for sensitive filter applications.
