Traditional arrays consisting of well-isolated elements are usually studied via analytical beamforming techniques. However, with the introduction of 5G networks, phased arrays need to be designed according to strict size and cost requirements, which may result in sub-optimal isolation. Beamforming optimization for such arrays needs to consider the individual element patterns, system S-parameters, varying impedance matching, active reflection coefficients and amplifier characteristics simultaneously, all of which are beyond the scope of classical formulations. In this workshop we’ll study the limits of the classical formulations and go beyond them with numerical techniques, enabling accurate, fast and robust optimization of compact arrays.
This workshop will demonstrate a design-to-test workflow for a COTS phased-array radar system using Analog Devices’ ADAR 1000 beamforming ICs and ADTR1107 Transceiver ICs. These products provide a cost-effective solution to phased array development for commercial and defense applications. The completed 4x4 module was developed by X-Microwave using their library of components inside Keysight’s PathWave System Design (SystemVue) software. Attendees will hear from all three companies about the design and test process and the importance of model-based engineering (MBE) approaches to achieve high performance design success. The completed system will be shown along with correlation between measured and simulated designs.
This session will describe how the DDC and mm-wave bandwidth options provide a multi-channel, coherent receiver with alternatives for bandlimited, tunable applications where the full instantaneous bandwidth of the scope is not needed. Key RF performance specs will be presented, as well as techniques for linking scopes for 8, 12, or more channels of coherent acquisition. The 89601B VSA software provides a convenient and powerful radar and pulse analysis application that is tightly integrated with the scope. Several live demos will highlight the powerful features discussed. We will close with an overview of other multichannel platforms available from Keysight.
Early deployments of 5G are rapidly under way. 5G features include enhanced mobile broadband, massive machine type communication, ultra-reliable and low latency connection, Vehicle-2X, and more. What does this mean to filter, amplifier, and antenna designers? This presentation distills the essentials of 3GPP NR standard specifications and demonstrates how Visual System Simulator (VSS) software within the NI AWR Design Environment platform can be configured for various scenarios envisioned for 5G.
Energy Efficiency, Linearity, Output Power and Bandwidth are the four key technical parameters of a Tx RFFE. Efficiency is the differentiator.
Increasing miniaturization and integration of multiple functions and channels into one device pose a new challenge for RFFE’s. Matching to real world environments is important, as the RFFE feeds the antennas for beamforming directly.
We will discuss various efficiency enhancements on the PA design while optimizing test time and improve sensitivity at the same time. Industry partners will round up the session offering an additional perspective.
Emerging wideband mmWave applications demand improved system performance to achieve higher data throughput using larger contiguous swaths of spectrum and higher-order modulation above 50 GHz.
Measuring EVM for wideband wireless communications is an industry-wide characterization which can help improve system performance. To measure the performance of a DUT, it is important to optimize the measurement system over a broad power range.
Understanding which types of errors contribute to EVM is essential to improving system design performance. Linear, nonlinear, and noise impairments will be explored, along with signal analysis tools to help gain insight and optimize system performance.
Achieving electromagnetic compatibility (EMC) for an intentionally radiating device is a complex task, beginning before any actual design activity. Understanding the regulatory EMC requirements and the impact of design choices on EMC performance is critical for meeting this guaranteed specification in a predictable manner. This workshop will begin by discussing the EMC requirements for 5G New Radio base stations, mobile terminals and ancillary equipment as defined in the 3GPP (and ETSI) technical specifications and illustrating the process of deriving the actual requirements. The workshop will continue with a discussion of key EMC concepts and recommended techniques for a successful design.
This workshop will cover the advancements in silicon technologies for mm-wave communication systems including 5G and Satcom. We will talk about IC technologies for silicon beamformers including circuit architectures, advanced packaging methods and silicon processes. We will also invite our partners to demonstrate their phased array systems using these silicon beamformers. The overall content will cover ICs and systems at Ku and Ka band.
With increasing bands, carrier aggregation, and MIMO, 5G front-end requires more filters. Various filter technologies such as SAW, BAW, and IPD compete for this market. These different filter technologies will be reviewed. IPD finds its unique area of applications with its advantage on size, performance, and cost. For 5G NR, IPD is especially suitable due to the high frequency and large bandwidth requirement. Different variants of IPD technologies such as silicon and TGV will be compared for 5G NR filters. To meet the additional requirement on sharp out-of-band rejection, IPD is integrated with BAW to achieve both bandwidth and rejection.
This workshop explains phase noise fundamentals, measurement, and its impact on performance of RF/microwave systems. We will compare different measurement instruments and techniques. We’ll describe the role of the phase detector and the use of cross correlation in optimizing sensitivity, and we’ll discuss the impact of reference sources on phase noise measurements. Residual and absolute phase noise examples and practical DUT measurements will be shown. Lastly, we’ll examine AM Noise measurement techniques.
Continuous expansion on boundaries of on-wafer measurements is driving the need for simultaneous development of unique VNA systems, innovative probe designs, and advanced calibration techniques. This workshop by Anritsu and MPI will describe key equipment parameters that both enable system performance while maintaining overall measurement integrity. Important aspects of VNA systems such as power control, raw and corrected port parameters that can affect calibration and measurement stability will be presented. Advancements in probe design and calibration techniques will be highlighted. The workshop will include wafer substrate considerations to obtain calibration and measurement optimization and ultimately DUT design success.
The 5G standard is both large and complex. In this workshop, we seek to demystify 5G signal construction, demodulation, analysis, measurements and conformance tests with a series of lab demonstrations, leveraging the 89600 VSA software with the UXA signal analyzer along with the Signal Studio software with the VXG signal generator. Besides serving as a world-class measurement tool, the VSA can also be used as a wonderful learning vehicle, enabling a student of a new standard to explore characteristics of his/her signal under test. We look forward to sharing the story of 5G signal construction, measurements and analysis.
Advances in quantum control used to encode information quantum processors, is critical for scaling quantum computing beyond current NISQ-era architectures. For the prevailing quantum computing paradigms, future generations of quantum control circuitry will need to operate at cryogenic temperatures.

Lake Shore Cryotronics, will share insights for wafer-level, microwave device characterization including device temperature, probing challenges, and quality of calibration at cryogenic temperatures.
This workshop presents the development of a Doherty PA offering higher PAE at output power backoff. Communication amplifiers must operate at larger OBO levels to keep devices in their linear region to reduce the impact of signals with PAPR power ratios. A design process will be demonstrated that covers characterization of the devices used in the main and peaking amplifiers (modeling Class-AB and Class-C GaN HEMTs), identification of optimum load impedances through load-pull analysis, network synthesis impedance matching, impedance inverter design, and design verification through EM analysis. Linearity performance will be simulated using a 5G test bench system-level analysis.
