Low-Loss Materials Key for High-Frequency Applications

 

KGK has developed a portfolio of laminate substrate materials designed to meet low-loss requirements. Laminates provide the backbone for increasingly complex circuits built on both rigid and flexible substrates. They provide mechanical integrity to flex circuits while allowing designers the freedom to fit circuits into the available footprint. All the materials in multilayer flex laminates must be chosen for their ability to combine mechanical flexibility with sufficient electrical performance
