Low Temperature Co-Fired Ceramic (LTCC) Parts and Material Vendors Entering the 5G International Supply Chain

Technology Overview

Low Temperature Co-Fired Ceramic (LTCC) Parts and Material Vendors Entering the 5G International Supply Chain.
Low Temperature Co-Fired Ceramic (LTCC) Parts and Material Vendors Entering the 5G International Supply Chain.

Due to the lack of leading domestic communication system manufacturers in Taiwan’s communications component industry, it is difficult for emerging communications industries such as 5G to enter the supply chain; typical holdups include obtaining specifications and gaining industrial advantages in the early stages. Together with Taiwan DuPont, ITRI has used the Low-Temperature Co-Fired Ceramic (LTCC) field verification platform and highprecision material process integration technology to achieve 250MHz bandwidth and passband loss below -1 dB for 5G FR1 Substrate Integration Waveguide (SIW). This overcomes Huawei’s patent restrictions on ceramic waveguide filters and has been verified by the manufacturer Nokia. In the future, ITRI will first obtain materials, design, manufacturing, and inspection certifications; at which point the technology will be transferred to domestic communication component manufacturers in order to help them enter the international 5G supply chain.
