ETS-Lindgren Announces Technical Contributions to IMS2021

5GNR, EMC, Automotive, and Wireless Topics to be Presented at International Microwave Symposium


CEDAR PARK, Texas May 20, 2021 ETS-Lindgren announced its technical contributions to the International Microwave Symposium (IMS) 2021, one of the industry's most significant microwave symposia, to be held June 7 - 10 at the Georgia World Congress Center in Atlanta, Georgia.  Hosted by the IEEE Microwave Theory and Techniques Society (MTT-S), the in-person symposium also features a virtual component scheduled for June 20 - 25.  ETS-Lindgren engineers will present as part of the Industry Workshops technical program as well as support a live demonstration in ETS-Lindgren's Booth #1527 as part of the IMS2021 in-person exhibition.


Jari Vikstedt, Director, Wireless Solutions with ETS-Lindgren, will present in the Industry Workshop "Performance Validation of 5GNR mmWave Devices: From Chipset to Production Line" scheduled for Tuesday, June 8, from 8:00 - 9:40 am EDT in Room 313/314.  Together with Allen Henley, Field Product Specialist with LitePoint, Mr. Vikstedt will address the unique challenges 5G New Radio (5GNR) technology presents to device manufacturers not only to find the space in which to place the chipset, but also to ensure the chipsets perform as intended in all possible usage cases.  RF testing of mmWave devices is performed using over-the-air (OTA) measurements, often employing multiple directional horn antennas to test a single device.  A typical mmWave manufacturing test system requires careful consideration of the chamber, test equipment, switches, horn antennas, and cabling.  While most design engineers and lab technicians are familiar with traditional OTA testing of wireless devices, today's modern mmWave devices present new challenges.  As part of this workshop, attendees will learn how these key OTA test system components work together to address these new challenges.  Key considerations and tradeoffs will be shared based on real-world applications.  The workshop will conclude with a case study of a currently deployed high-volume mmWave production test solution.


"With the extensive R&D involving 5GNR technology, chipsets are required to handle increasing levels of technology, from typical digital data to radiating antenna elements in novel antenna array designs.  5GNR's low-frequency range, known as FR1, covers up to 7.2 GHz.  RF testing of FR1 devices is similar to what is currently performed with WiFi and LTE.  The high-frequency band, FR2, covers 24 GHz and higher; however, this band presents significant new challenges for RF testing," explained Mr. Vikstedt.   "FR2 requires a new approach and all new test system components.  Manufacturers are now faced with learning this new technology and providing high quality RF performance verification while minimizing the cost of testing.  Allen and I will share solutions to these challenges in our workshop."


Also on Tuesday, June 8, from 10:10 - 11:30 am EDT in room 313/314, Ross Carlton, EMC Test Systems Engineer with ETS-Lindgren, has organized and chairs the Industry Workshop "Emerging EMC Requirements for 5G mmWave Devices."  Mr. Carlton will share some lessons learned when addressing performance validation testing of 5G mmWave devices from an electromagnetic compatibility (EMC) perspective.  Garth D'Abreu, Director, Automotive Solutions with ETS-Lindgren, will present "Wireless Coexistence Implications on Automotive Test and Measurement Applications," also in this workshop.  Other contributors include Jason Coder, Shared Spectrum Metrology Group Leader, National Institute of Standards and Technology (NIST) and Bob DeLisi, TCB/FCB/NB Certification Engineer, Underwriters Labs (UL).  Achieving EMC for 5G devices is dependent upon the existence of achievable and appropriate regulatory requirements along with meaningful test methods for demonstrating compliance.  The primary body in North America focused on developing EMC test methods for wireless and 5G devices, for both licensed and unlicensed transmitters, is Accredited Standards Committee C63 of the American National Standards Institute (ANSI).  This workshop will provide an overview of C63 and the standards most relevant to manufacturers of 5G mmWave devices, the emerging technology addressing wireless coexistence, as well as transmitter performance characterization and validation.  Time will be allocated for attendee Q&A throughout the workshop.

As an active technical contributor to the ASC C63 committee, Mr. Carlton will provide the demonstration "Measurement of mmWave Radiated Spurious Emissions" during IMS2021.  Visitors to ETS-Lindgren's Booth #1527 will see this hands-on application related to the content presented in the Industry Workshop.  The demonstration presents a multi-axis effective isotropic radiated power (EIRP) and power spectral density (PSD) measurement solution for a 5G mmWave radiating device, as required by FCC Part 30, ETSI/EN 300 400, ETSI/EN 305 550, and other relevant specifications such as those from the 3GPP.  Compatibility with traditional semi-anechoic chambers, common for EMC measurements, and fully anechoic rooms make this demonstration applicable to nearly any EMC or RF lab that handles wireless intentional transmitters.  The demonstration will be of a radiated spurious emissions (RSE) measurement in the mmWave frequency range and will be accompanied by a presentation that explains the applicable standards, highlights the challenges associated with making the RSE measurement, and describes the measurement automation employed.
