Band-Pass Filter Measures 0.3-mm Thick

Reportedly the thinnest available, the company’s 1005-size thin-film band-pass filter measures 0.3-mm thick. Overall, the device measures1.0 mm x 0.5 mm and targets portable applications including ensuring signal quality in wireless LANs for mobile phone use, Bluetooth modules, Bluetooth-compatible headsets, and other devices. The company’s thin-film technologies, developed through hard-disk drive magnetic head manufacturing and formed thin-films of copper wiring, insulation material, and dielectric material on a ceramic substrate, claim responsibility for this significant reduction in size. The device is set for production in January 2009. For more information, call TDK USA CORP., Garden City, NY. (516) 535-2600.
