August 4, 2020— NI (Nasdaq: NATI) announced today at the 2020 International Microwave Symposium (IMS) that it has collaborated with Eta Wireless to fully support ETAdvanced, the industry’s first digital envelope tracking (ET) technology for millimeter wave (mmWave) 5G RF front-end devices. Developed by Cambridge-based Eta Wireless, ETAdvanced extends battery life, data rates and connectivity range for smartphones, wearables and IoT devices.
ETAdvanced solves the power efficiency challenge that has long plagued the RF front end, such as the wideband power amplifier (PA) in 5G devices, which wastes a lot of power in the form of heat, thereby significantly shortening battery life. ETAdvanced technology can make full use of the envelope information of the signal and only deliver the power required at the moment, thereby improving the efficiency of the amplifier.
Using NI software-interconnected PXI systems to fully support ETAdvanced technology enables tight synchronization of sophisticated digital edge deployment, broadband 5G New Radio (NR) generation, and millimeter wave vector signal transceiver (VST) analysis.
These technologies have helped Eta Wireless achieve a 3x increase in data rate and doubled PA output power, solving the core power and heat dissipation issues of 5G millimeter wave deployment.
Under a given power budget, the increase in coverage and throughput makes ETAdvanced technology a key driver for millimeter wave 5G radios.
