Microwave devices using advanced ULTCC technologies

ULTCC (Ultra-Low Temperature Co-fired Ceramics) is an advanced technology that enables the co-firing of ceramics and metals at lower temperatures compared to traditional LTCC (Low Temperature Co-fired Ceramics). One of the main advantages of ULTCC is its lower firing temperature, typically below 750°C, which allows for broader material compatibility, including sensitive components that could be damaged at higher temperatures. Additionally, ULTCC offers better thermal stress management, reducing the potential for damage during the manufacturing process. It can also be more cost-effective due to reduced energy consumption, while providing enhanced design flexibility for complex geometries.

ULTCC technologies offer significant advantages for applications like RF and microwave devices, sensors, power electronics, medical devices, wearable technology, automotive electronics, and telecommunications. These benefits stem from improved performance, enhanced reliability, reduced costs and broader material compatibility due to lower firing temperatures. ULTCC provides sustainability solutions to EU green deals. All the materials compositions used in ULTCC technology is based on RoHS and REACH regulations.
