Keysight Technologies, Inc. (NYSE: KEYS) and Nokia Bell Labs are
demonstrating component and radio frequency integrated circuit
(RFIC) characterization for 6G subterahertz (sub-THz) radio
frequency (RF) applications in the D- and E-bands at the
International Microwave Symposium 2023 (IMS 2023) in June.
Delivering the extreme data speeds, ultra-low latency, and
near-infinite bandwidth of 6G will require the use of sub-THz
spectrum. However, sub-THz frequencies have not traditionally been
used for cellular communications due to their propagation
characteristics, which present signal integrity and path loss
challenges that can negatively impact performance. To help mitigate
these challenges, Keysight and Nokia Bell Labs have been
collaborating to develop characterization techniques to test active
sub-THz components, such as amplifiers, mixers, and frequency
converters, to ensure they do not introduce additional signal
distortion into communications systems.
The collaboration’s most recent achievement will be presented at
Keysight’s booth #835 at IMS 2023. Built on the Keysight PNA-X
Vector Component Analyzer (VCA) solution, the demonstration
characterizes a Nokia power amplifier (PA) developed for use in 6G
D-band wireless communications systems and designed to operate with
a low error vector magnitude (EVM). Using the Keysight N5290A PNA
Millimeter Wave System, Nokia Bell Labs can accurately detect the
PA’s low EVM, which is a measure of the signal distortion
introduced into the communications system by the component. With
these measurements, Nokia Bell Labs can better understand the PA’s
performance to optimize its 6G transmission system design.
Keysight and Nokia Bell Labs are also partnering to showcase an
E-band test solution at IMS 2023. The demonstration features the
Keysight N9042B UXA Signal Analyzer used in combination with the
V3050A Signal Analyzer Frequency Extender to measure a Nokia
transceiver RFIC designed for use in an E-band system for backhaul
applications.
To help network equipment manufacturers, semiconductor
companies, and device makers address the bandwidth and performance
demands of 6G, Keysight offers a 6G Sub-THz R&D Testbed. The
wideband sub-THZ testbed features an arbitrary waveform generator
(AWG) that generates a wideband intermediate frequency (IF), which
is upconverted to H-band (220-330 GHz). The signal is downconverted
to an IF, digitized with a UXR high-performance oscilloscope, then
demodulated and analyzed using PathWave Vector Signal Analysis
(VSA) software.
Shahriar Shahramian, Head of RFIC & Packaging Lab, Nokia
Bell Labs, said: “At Nokia Bell Labs we continue to push the
carrier frequency and complexity of our RFIC, packaging, and module
integration. With these advancements we move the frontier of what
is possible from 6G wireless and optical communication systems.
Consequently, the test and measurement industry plays a vital role
to enable the complex characterization demanded from our devices
and to reduce our time to market. We have been working closely with
Keysight throughout our design and verification journey. Keysight
continues to deliver innovation in both their software and hardware
6G measurement platforms, which we rely on for characterizing our
next generation systems.”
Giampaolo Tardioli, Vice President for Keysight’s 6G and Next
Generation program, said: “With 6G, we are on the cusp of
realizing an unprecedented new era of high-speed, high-reliability,
and flexible mobile connectivity that promises to transform human
communications. This shift will be driven by the use of the
subterahertz spectrum, which will give us the speeds needed to
enable 6G use cases such as augmented reality and autonomous
transportation. By working closely with global industry partners
like Nokia Bell Labs today, Keysight is helping to create the 6G
technologies needed for tomorrow’s mobile networks.”
The Keysight and Nokia Bell Labs 6G D-band PA characterization
demonstration will also be presented at Radio Frequency Integrated
Circuits Symposium 2023, which is co-located with IMS 2023.
