Recently, Keysight Technologies and the University of California, San Diego announced that the ultra-long bidirectional phased array link in the 60 GHz band has been successfully verified. Within a link distance of 300 meters, a 32-element array can achieve data rates above 2 Gbps over a full scan angle of up to ±45 degrees. At a distance of 100 meters, the data rate can reach 4 Gbps in most scanning angles; 500 Mbps can be reached within 800 meters. The results of initial testing by leading wireless providers show that the system can provide data content to eight households simultaneously over a distance of 300 meters.
The entire phased array will consume 3W to 4W of DC power in transmit (Tx) or receive (Rx) mode. This is due to the high-performance system-on-chip (SoC) design offered by the University of California, San Diego, using the third-generation silicon germanium BiCMOS standard buried collector (SiGe BiCMOS SBC18H3), the world's leading wafer fabrication leader, TowerJazz. Process manufacturing.
Keysight's hardware and software support engineers quickly design system prototypes, implement link balancing, and perform advanced performance measurements at 2GHz modulation bandwidth. The core hardware elements are the M8195A arbitrary waveform generator, the E8267D PSG vector signal generator and the DSOS804A HD oscilloscope.
The University of California, San Diego uses Keysight's Signal Studio software to define and generate 60GHz 802.11ad waveforms, laying a solid foundation for development work. Keysight's 81199A Wideband Waveform Center software helps teams connect transmitters and receivers, apply digital pre-distortion and improve error vector magnitude (EVM) performance. The team also used Keysight's 89600 VSA software to perform advanced signal demodulation and analysis.
Academician of the National Academy of Engineering, renowned professor at the Jacobs School of Engineering at the University of California, San Diego, and Gabriel M. Rebeiz, president of the wireless communications industry, said: "This is the second time that the University of California, San Diego has partnered with Keysight to demonstrate high-performance phased array 5G. The communication link achieves gigabits per second at previously unimaginable distances and very low power consumption. Keysight's equipment and software, as well as Tower Jazz's SBC18H3 technology, have played a key role in our success."
The H3 process is part of the TowerJazz terabit platform, which includes advanced 240 GHz SiGe bipolar transistors and CMOS analog devices. With extremely low noise, the platform is ideal for use in the 60 GHz band and high frequency applications such as radar, optical wireless communications and emerging wireless standards.
The University of California, San Diego, who contributed primarily to this achievement, included electrical engineering graduate students Bhaskar Rupakula and Ahmed Nafe; and electrical engineering post-doctors Samet Zihir and Tsu-Wei Lin. They all praised the quality of Keysight's hardware, software and technical support.
Dr. Mark Pierpoint, Vice President of Keysight Technologies and General Manager of Internet Infrastructure Solutions, said: "The results of our ongoing collaboration with the University of California, San Diego, and the strengths demonstrated in the field of millimeter wave technology provide key evidence for 5G feasibility. In particular, fixed broadband use cases are the focus of many pre-standardization efforts. We will continue to increase investment and introduce innovative solutions to enhance and promote the development of next-generation wireless communications."
All Keysight products used in the development of 5G communication links are available. The phased array SoC at the University of California, San Diego is also available.
The category introduction of Solar Light can be elaborated from multiple dimensions. The following is a comprehensive category introduction:
Solar Light, taken literally, refers to the light produced by solar energy, i.e., sunlight or daylight. However, in the commercial and technical fields, the category of Solar Light may more broadly cover solar related lighting equipment, inspection equipment, and various products that use solar energy for light conversion and applications.
Solar Light products usually have the following technical characteristics:
Environmental protection and energy saving: The use of renewable energy - solar energy to work, reduce dependence on traditional energy and environmental pollution.
Intelligent control: Some products have intelligent control function, which can automatically adjust the working state according to the lighting intensity, time and other conditions.
High efficiency and stability: The use of advanced conversion technology and materials to improve energy conversion efficiency and product stability.
Portable and easy to use: Some portable solar equipment such as flashlights, lamps and other small design, easy to carry and use.
With the global attention to renewable energy and the continuous progress of Solar energy technology, the market prospect of Solar Light is very broad. Especially in the home, commercial, industrial and other fields of application will continue to expand, to contribute to energy saving and sustainable development. At the same time, with the continuous innovation of technology and the continuous upgrading of products, Solar Light products will be more intelligent, efficient and convenient to meet the growing needs of people.
