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.
