NEC develops compact amplifier for 5G base stations
NEC Corporation has developed a high-efficiency, compact Power Amplifier Module (PAM) for the sub-6 GHz band, designed for integration into 5G base station Radio Units (RUs). PAMs are electronic components that amplify signals for long-distance radio transmission, and their power consumption accounts for approximately 75 percent of the total power consumed by an RU. By integrating this high-efficiency PAM into RUs, NEC aims to reduce device power consumption and size, thereby contributing to reduced operati
