Taiyo Yuden's latest lines of chip filters are designed to optimise the performance, while minimising the size, of mobile phones.

The compact EIA 0603 size multilayer dual low pass filter is designed for use with multi-band smartphones, while two optimised EIA 0805 size multilayer diplexers were developed for use with mobile phones.

Taiyo Yuden chip filters for the cellular band field are based on the company's development of multilayer filters and chip antennas for non-cellular band applications, such as wireless LAN, Bluetooth and GPS.

One of the smallest chip filters in its class, the EIA 0603 size dual low pass filter F1168D087018 measures 1.6 x 0.8mm with a maximum height of 0.45mm.

With the introduction of Taiyo Yuden's F1168D087018, two differing frequency band low pass filters (the GSM telecommunication standard low band and a high band) are combined into a single part.

This reduction in parts and surface-mount area contribute to a smaller overall device size.

Smartphones equipped with dual low pass filter technology meet the wireless communication standards that are required to achieve high-speed data transmission.

Taiyo Yuden's EIA 0805 size F1212P089208 and F1212P089213 (2.0 x 1.25 x 0.9mm each) multilayer diplexers are optimised for the RF send/receive systems of multi-band mobile phones.

Two antennas for different frequency bands are used for sending and receiving RF signals, with a diplexer that performs the required multiplexing and demultiplexing operations.

Employing its component design technology, multilayer ceramic technology, high-frequency component materials and simulation technology, Taiyo Yuden produces compact multilayer diplexers that reduce the required space for a multi-antenna system.

Custom solutions are also available to meet customer-specific demands.

The acquisition of Fujitsu Media Devices by Taiyo Yuden has increased the company's offering to include the F1212P089208 and F1212P08921, as well as other high-frequency components for cellular band applications.
