Overview

Murata Manufacturing Co., Ltd. will be introducing to the market a SAW duplexer (1.8 x 1.4 mm) that adopts original technology to achieve higher steepness, a lower dissipation factor and more stable temperature characteristics than SAW devices up till now. As a result, frequency bands that could not be supported by conventional SAW devices are now supported. Mass production is scheduled to begin in early 2017. 

Background

SAW devices filter out various frequencies, making them a vital component in smart phones and other communication terminals. In recent years, there has been increased demand for steep, low-dissipation-factor filter characteristics and stable temperature characteristics as a result of higher communication frequencies and closer proximity of frequency bands, both areas that could not be sufficiently supported by conventional SAW devices. 

Murata has applied its unique expertise in the development of a new technology for propagating SAW energy more effectively than ever before and thereby commercialized a new SAW duplexer with more advanced performance, a lower cost, and a more compact size that can accommodate frequency bands not supported by conventional SAW devices. This has allowed Murata to expand its lineup of SAW devices compatible with a broad range of the frequency bands expected to increase in the future. Murata hopes that this development will enable quick response to future market demands and help make RF circuits even smaller and improve their performance.

Terminology

SAW

An abbreviation for “Surface Acoustic Wave.” SAW refers to vibration that concentrates and propagates along the surface of a material. 

Duplexer

An antenna-sharing device. A duplexer is used to share transmission/reception antennas and electrically isolate the transmission and reception paths in wireless communications circuits where transmission and reception are carried out simultaneously on different assigned frequencies.
