CLTE-MW Substrate: The Key to Exceptional Performance
CLTE-MW copper clad laminates form the backbone of our PCB’s superior performance, engineered to meet the demands of 5G, millimeter wave, and thickness-constrained high-frequency applications:
CLTE-MW laminates provide PCB designers with a high-performance, cost-effective material that is well-suited for applications limited by physical or electrical thickness constraints. This unique laminate system comes in seven thickness options, ranging from 3 to 10 mils, ensuring optimal signal-to-ground spacing for 5G and other millimeter wave applications. Reinforced with spread glass and high filler loading, CLTE-MW laminates help reduce the impact of high-frequency glass weave on electromagnetic wave propagation. As a ceramic-filled PTFE composite, CLTE-MW is specifically developed for the 24GHz to 77+GHz frequency range, delivering low-loss performance without the high cost of premium alternatives.
Engineered for cost-effectiveness and versatility, CLTE-MW addresses the critical need for low-loss, thin-substrate solutions in modern high-frequency electronics. Its spread glass reinforcement and high filler loading not only reduce signal distortion but also enhance mechanical stability, making it ideal for demanding environments such as military and aerospace applications.
