Murata Debuts World’s First XBAR High-Frequency Filter for 5G, Wi-Fi 7, and 6G Networks

Murata Manufacturing Co., Ltd. has begun mass production and commercial shipment of the world’s first high-frequency filter utilizing XBAR technology. Developed through a collaboration between Murata’s Surface Acoustic Wave (SAW) filter expertise and XBAR technology from its subsidiary Resonant Inc., the filter enables signal extraction with low insertion loss and high attenuation, essential for modern wireless technologies such as 5G, Wi-Fi 6E, Wi-Fi 7, and emerging 6G networks.

The filter addresses the growing demand for reliable high-frequency communications driven by 5G deployment and the anticipated development of 6G. It also supports wireless local-area network (WLAN) standards like Wi-Fi 6E and Wi-Fi 7, which operate in higher frequency domains to deliver ultra-fast data rates. The filter overcomes challenges faced by traditional Low Temperature Co-Fired Ceramic (LTCC) and conventional Bulk Acoustic Wave (BAW) filters, which struggle with out-of-band interference, battery performance optimization, and space constraints.

The XBAR-based filter achieves high attenuation while maintaining wide bandwidth and low signal loss. Its structure uses comb-shaped electrodes and a piezoelectric single-crystal thin film to ...
