Operating results

For fiscal 2017, circuit ceramic modules and RF sub modules for high-end smartphones faced sluggish sales due to a reduction in the Murata share of orders won from a specific customer. However, short-range wireless communication modules for products such as smartphones and personal computers were successful. Sales in multilayer resin substrates also achieved substantial growth as an increasing number were used in high-end smartphones. As a result, overall net sales were 395.0 billion yen (up 21.3% year-on-year).

Connectivity modules

Connectivity modules are compound components for wirelessly accessing the Internet or other devices from various devices.
These are used in various types of familiar devices such as smartphones, tablets, digital cameras, home appliances, and car navigation systems, and enable users to download and upload photos and music from the Internet, call hands-free while driving, and confirm air conditioner operation and turn
switches on and off remotely.
An IoT society where all types of objects around us are connected to the Internet is just around the corner. In this IoT society, various types of devices will have wireless communication functions. Requirements vary depending on use such as low power consumption, high-speed data communication, high reliability, and low profile.
Murata provides products compatible with new communication technologies such as WiFi, 5G, and V2X through design technologies for smaller and higher performance products alongside software technologies to enhance connectivity, while contributing to the development of an IoT society as our mission in creating the future of electronics.


MetroCirc™

MetroCirc™ is a multilayer resin substrate comprising resin sheets using LCP film and copper foil sheets stacked in many layers employing Murata’s multilayer technology. It has exceptional RF characteristics and does not require any adhesion layer, making it thinner. Furthermore, it facilitates a flexible bending process and is thus said to be an origami-like substrate. Through various circuit designs, it can function not only as a substrate but also as a transmission wire component, or have integrated coil functionality. Thanks to these characteristics, it contributes to smaller, thinner, and higher performance smartphones and wearable devices.
Because of its RF characteristics and low transmission loss properties, MetroCirc™ will prove its worth and is expected to expand its uses for various applications including substrates for millimeter wave modules, millimeter wave transmission lines, and wired high speed differential transmission lines. Murata will continue to offer high value added products for resolution of customer issues by making the most of Murata’s advanced film and multilayer technologies.

RF modules

Murata’s RF modules are multifunctional and high performance electronic component units that realize an analogue high frequency circuit that controls communications among wireless devices by integrating various key devices.
This module is comprised of passive devices such as SAW filters which demultiplex high frequencies and LC filters, high power amplifiers in transmission, low distortion amplifiers in reception, antenna changeover switches, and other semiconductor devices, and is actively used for various types of wireless devices including smartphones and other mobile phones and tablet PCs.
With the arrival in the future of the high speed and large capacity 5G service, which will enhance people’s quality of life, RF modules for realizing dual connectivity in addition to multiple frequency bands and carrier aggregation will become necessary.
Murata, which internally develops various key devices that form the basis for module configuration and package technologies for modularization, is able to carry out integrated production. As a result, Murata has a strong competitive advantage in terms of business speed, production capability, and quality, in addition to performance.
Murata will leverage these competitive advantages to propose RF modules most suitable to new markets and customer needs and aim to be a leading company to be selected by customers.
