TDK-EPC’s new TFSB series of TDK thin-film band pass filters have a footprint of 1.0 x 0.5 mm2 and an insertion height of just 0.3 mm. The new filters are designed for the 2.4 GHz and 5 GHz bands, making them suitable for Bluetooth and WLAN applications in smartphones and other mobile phones. The new filters achieve low-loss signal transmission and high attenuation of unwanted signals, resulting in a high signal quality. The band pass filters were developed by using a thin-film micro-wiring technology that TDK developed for the manufacturing of magnetic heads for hard disk drives.Learn more from TDK-EPC.
