Development of TransferJet™-compatible Wireless Device  World's Smallest!

Overview

Murata Manufacturing Co., Ltd. has developed a wireless device compatible with the close-proximity wireless data transfer technology The device is embedded with a next-generation IC and a Murata high-frequency filter (LFB214G48CGD471) .

*TransferJet™ is a trademark of Sony Corporation.

Background

TransferJet™ is a technology developed to enable anyone to use close-proximity wireless data transfer easily and with no stress. TransferJet™ enables high volumes of music, image, movie and other data to be transferred at high speeds with ease simply by bringing two devices into proximity with each other. It is expected to have a bright future as a communications interface between mobile devices such as smartphones and digital cameras, and between mobile devices and PCs, TVs, etc.

Miniaturization of components is demanded as the functions of electronic equipment become increasingly sophisticated. The application of Murata's unique high-frequency design technology and component embedding and multilayer process technologies has enabled the development of a small, low-profile wireless device compatible with TransferJet™ standards.

Features

The developed device employs a next-generation IC that does not require external ROM* or oscillators. This IC is embedded in a substrate using Murata's component embedding technology, enabling the realization of the industry's smallest dimensions. The device also incorporates a high-frequency filter and peripheral circuit components, reducing the space required for mounting.

Terminology

*ROM (Read Only Memory) : Data storage media that can only be read

Applications

Electronic devices, in particular smartphones, tablets, and notebook PCs
