Taiyo Yuden announced its latest lines of chip filters. The compact EIA 0603 size multilayer dual low pass filter is designed for use with multi-band smartphones, while two new optimized EIA 0805 size multilayer diplexers were developed for use with mobile phones. The EIA 0603 size dual low pass filter FI168D087018 measures 1.6 mm x 0.8 mm with a maximum height of 0.45 mm. With the introduction of Taiyo Yuden’s FI168D087018, two differing frequency band low pass filters (the GSM telecommunication standard low band and a high band) are combined into a single part. The company’s new EIA 0805 size FI212P089208 and FI212P089213 (2.0 mm x 1.25 mm x 0.90 mm each) multilayer diplexers are optimized for the RF send/receive systems of multi-band mobile phones. The company asserts its component design technology, multilayer ceramic technology, high frequency component materials and simulation technology results in multilayer diplexers that drastically reduce the required space for a multi-antenna system.
