As LTE or LTE-A spreads to the world for mobile communication devices, companies conc- entrate on improving the efficiency of batteries. Among many technol- ogies, Envelope Tracking Power Amplifier and Doherty Power Amplifier technologies, which improve the efficiency up to 30 percent, are receiving the spotlight. For the trend, POSTECH and Rohde & Schwarz made an agreement to develop technology to improve the efficiency of mobile communication batteries on Feb. 11 1:30 P.M. at LG Cooperative Electronics Engineering Building in POSTECH. Rohde & Schwarz is a company which has an expert supply chain and service network of over 70 nations. It produces various equipment related to communication, broadcasting transmitters, and research. For the agreement, Rohde & Schwarz promises to offer high technology equipment such as a power amplifier and telemeter system. Professor Kim Bumman (EE), who made the agreement, is a director of Mondithic Microwave Integrated Circuit Laboratory in POSTECH. He is an authority on the technology of power amplifiers for mobile communication. Through their joint effort, the development of core technology is expected to accelerate.
