IBM and Ericsson launch 5G base station-based silicon-based millimeter-wave phased-array integrated circuits
IBM and Ericsson jointly announced on Tuesday the announcement of the successful launch of a silicon-based millimeter-wave phased-array integrated circuit for use in future 5G base stations. According to the announcement, the phased-array IC operates at 28GHz millimeter-wave frequency and has been successfully demonstrated in phased-array antenna modules, paving the way for future 5G networks. The product is a two-year collaboration between the two companies (as early as the end of November 2014, the two companies started a collaboration on 5G antenna development) that combines IBM's high-integration phased array millimeter-wave integrated circuits and antenna packages The advantages of the solution, and the accumulation of Ericsson technology in the design of mobile communication circuits and systems. IBM officials said the module contains four monolithic integrated circuits and 64 dual-polarized antennas, the module size is about 2.8 inches * 2.8 inches (about 7.1 cm * 7.1 cm), almost the mainstream Half the size of the phone, IBM said it is the size necessary to support the widespread deployment of 5G, especially in indoor spaces and dense metropolitan areas. IBM also pointed out that the phased array antenna module parallel dual-polarized mode of operation can form two beams, while maintaining the receiving and transmitting mode, thereby enabling the service to double the number of users, the design also supports less than 1.4 degrees Beam scanning accuracy. Dario Gil, Science and Vice President, IBM Research Center, said: "The evolution of the 5G millimeter-wave phased array is a major breakthrough not only because of its compact size and low cost, but also for network equipment providers and operators The solution to business appeal is more because of its potential to thrive in a connected society and to inspire new ideas and innovations that have never been thought before. " Based on IBM's introduction, the phased-array IC is based on the company's previous millimeter-wave operation, including the monolithic millimeter-wave radio developed in 2006, the highly integrated millimeter-wave phased array receiver for mobile and radar in 2013, As well as mobile phone how to communicate in millimeter-wave frequency of related exploration and research. At the 2017 International Solid State Circuits Conference in San Francisco today, IBM also unveiled a paper describing how IBM and Ericsson work together to develop the phased-array IC, titled "A 28GHz 32-Element Phased-Array Transceiver IC with Concurrent Dual Polarized Beams and 1.4 Degree Beam-Steering Resolution for 5G Communications ". Last year, Ericsson announced that it will roll out the world's first commercial 5G radio, the AIR 6468, for large-scale and multi-user MIMO by the end of 2017. This new radio will provide a hybrid system of advanced antennas and controllable ports for beamforming, large-scale MIMO and multi-user MIMO. Ericsson said the AIR 6468 will provide operators with 5G access to all components of the network in conjunction with the company's previously announced 5G Plug-Ins and current Radio System Baseband 5216. Of course, while communications equipment manufacturers are pushing the popularity of 5G technology, carriers around the world are also actively preparing for the deployment of next-generation wireless communications technologies. In the United States, Verizon has piloted the commercialization of 5G networks in 10 cities, and AT & T has also conducted a 5G commercial test with Intel and will test 5G technology in Austin and Indianapolis in the coming months. Different from other competitors, Sprint and T-Mobile are more focused on the deployment of mobile 5G.
