Murata Manufacturing Co., Ltd. acquired Eta Wireless Inc. for approximately 16 billion yen. It plans to introduce Eta Wirless technology into communication products in the next few years to improve product energy efficiency. On the other hand, its technology is also conducive to Murata's research and development of next-generation 6G wireless Communication technology.
With the popularization of 5G and the higher performance of smart devices, the challenge of energy consumption is also increasing. The application of energy-saving technology is the key to strengthening the competitiveness of products. Relying on hardware manufacturing and simulation methods to reduce the power consumption of electronic components is limited. To achieve even better results, a method that combines signal processing technology and digital power management technology must be used to effectively control the radio frequency circuit.
The Digital Envelope Tracking technology mastered by Eta Wireless Inc. can save the power of signal transmitters used in devices such as smartphones and tablets, and it also has technology that can effectively control circuit voltage. Through the proprietary PMIC, the voltage required by the radio frequency circuit is digitized and optimized to support broadband signals such as 5G, which helps to suppress excessive power consumption. The DPD algorithm further reduces power consumption through a unique algorithm, minimizing the distortion and noise in the RF circuit.
Murata has a leading position in the RF front-end field. This acquisition aims to collaborate with Eta Wireless's Digital Envelope Tracking technology to jointly solve the key power and heat dissipation challenges of 5G and provide superior RF products.
