2005年10月,无线通信模块制造商德国EpcosAG公司运用LTCC技术开发出5GHzWLAN的平衡/不平衡阻抗转换器,以及该转换器所使用的WLAN物理层电路模块。两者均运用了左手材料传输线路设计技术(见图A-2)。这是第一款左手材料实用化的器件。该阻抗转换器是平衡电路和非平衡电路连接时所
In October 2005, Epcos AG, a manufacturer of wireless communication modules, used LTCC technology to develop a 5GHz WLAN balanced / unbalanced impedance converter and WLAN physical layer circuit module used in the converter. Both use left-handed material transmission line design techniques (see Figure A-2). This is the first practical device for left-handed materials. The impedance converter is balanced circuit and unbalanced circuit connection
