Multilayer Diplexers and Dual Low Pass Filters

Taiyo Yuden's chip filters and diplexers answer demand for smaller, higher capability mobile phones

Designed for use with multiband smartphones, Taiyo Yuden's 1.6mm x 0.8mm (0.45mm maximum height), EIA 0603 size dual low pass filter, FI168D087018, is one of the smallest in its class. The FI168D087018 combines two differing frequency band low pass filters (the GSM telecommunication standard low band and a high band) into a single part for a smaller overall device size.

The new EIA 0805 size FI212P089208 and FI212P089213 (2.0 x 1.25 x 0.90mm each) multilayer diplexers are optimized for the RF send/receive systems of multi-band mobile phones. These compact multilayer diplexers drastically reduce the required space for a multi-antenna system.

Taiyo Yuden chip filters are based on their extensive experience with and development of multilayer filters and chip antennas for non-cellular band applications, such as wireless LAN, Bluetooth® and GPS. Their diplexer technology is a result of the company’s component design technology, multilayer ceramic technology, high frequency component materials, and simulation technology.
