Keysight Technologies, UC San Diego collaborate on 5G communication

Keysight Technologies, Inc. (NYSE: KEYS), with the University of California San Diego has announced a new bidirectional phased-array link in the 60 GHz band, the company said.

At a link distance of 300 meter, the 32-element array achieved a data rate of greater than 2 Gbps over all scan angles up to ±45 degrees. Data rates were 4 Gbps at 100 m and 500 Mbps at 800 m over most scan angles. Initial tests by a leading wireless provider suggest the system can deliver content to eight homes at a time at up to 300 m.

The entire phased array consumed 3 to 4 W of DC power in either its transmit (Tx) or receive (Rx) modes. This is due to the high-performance system-on-a-chip (SoC) designs UC San Diego created using the third-generation silicon germanium BiCMOS standard buried collector (SiGe BiCMOS SBC18H3) process from TowerJazz, the global specialty foundry leader.

Keysight hardware and software enabled rapid prototyping of the system, as well as link equalization and state-of-the-art performance measurements at 2 GHz modulation bandwidth. Central hardware elements were the M8195A arbitrary waveform generator, E8267D PSG vector signal generator and DSOS804A high-definition oscilloscope.

UC San Diego used Keysight´s Signal Studio software to define and generate the 60 GHz 802.11ad waveform, which was the basis for development. Keysight´s 81199A Wideband Waveform Center software helped the team link Tx and Rx, apply digital pre-distortion and improve error vector magnitude (EVM) performance. The team also used Keysight´s 89600 VSA software to perform demodulation and analysis of advanced signals.

The H3 process is part of the TowerJazz Terabit Platform, which includes state-of-the-art 240 GHz SiGe bipolar transistors and CMOS analog devices. With unequalled low noise, the platform is a technology of choice for use at 60 GHz and in high-frequency applications such as radar, optical wireless communication and emerging wireless standards.

All Keysight products used in the development of the 5G communication link are available now. UC San Diego´s phased-array SoCs are also now available.

The development of 5G depends on up-to-date tools that let designers easily explore new signals, scenarios and topologies. Keysight´s 5G solutions are ready to enable deeper insights as development evolves with the standard. In design and test, Keysight is helping industry leaders innovate across new and existing technologies as they transform ideas into reality.

The University of California San Diego participates in mixed-signal, microwave and mm-wave RFICs, digital communications, applied electromagnetics, optics and nano-electronics research, and is home to the Center for Wireless Communications.
