KYOTO — Murata Manufacturing said Friday it has acquired a U.S. developer of power-saving technology for smartphones, boosting its capabilities in a key field for devices with steadily growing energy needs.
The Kyoto-based manufacturer, which supplies parts for Apple iPhones, will purchase Eta Wireless for roughly 16 billion yen ($145 million).
Murata plans to bring efficient communications components featuring Eta’s technology on the market within the next few years, as well as develop technology for the eventual advent of sixth-generation wireless.
Massachusetts-based Eta’s technology reduces power consumption by wireless communication components — one of the most energy-hungry parts of a mobile device after the display and CPU — improving battery life for smartphones, tablets and other devices.
The company has developed a proprietary power management chip to optimize voltage in radio frequency circuits, as well as an algorithm that can further reduce energy usage.
Higher-frequency waves, such as the millimeter-wave spectrum often used by fifth-generation wireless technology, require more power, on top of the increasing energy consumption of high-performance smartphones. Because larger batteries make handsets bulkier, device makers are looking for other ways to compensate for these energy needs.
