Traditional fabrication approaches of Microwave/mmWave devices have material, geometry, tolerance, and/or repeatability challenges. New 3D printable resins with desirable Microwave/mmWave characteristics are enabling 3D DLP manufacturing of low-loss and low-dielectric constant material for prototyping and production. This whitepaper discusses applications of this 3D dielectric structure fabrication process.
For reliable and efficient system YOUR TASK verification and debug of DDR3/DDR4 memory designs, comprehensive compliance test and analysis tools are required. While measurement capability and usability are critical to speed up the verification and debug process, it is equally important to choose the right probing solution and use advanced techniques to improve overall measurement accuracy.
As the demand for higher frequencies and wider bandwidths continue their relentless march upward, RF connectors need to keep up with, or even exceed, demands. Mating the RF connector to a PCB or substrate requires careful consideration of several factors to get the full performance out of the connector. This white paper will provide an understanding of what makes successful launches work, what knobs to turn, and design guidelines to make connector launches perform well as the industry moves toward 100 GHz bandwidths.
The objective of this Rohde & Schwarz white paper is to provide a concise technology overview of 5G non-terrestrial networks with the author's background based on the wireless ecosystem.
This eBook explores GaN applications and highlights the capabilities of the technology. The first few articles describe applications where GaN’s high power, high temperature and radiation tolerance may prove useful: LEO satellites, EW, and hypersonic weapons while the remaining articles cover “hands on” topics covering GaN technology.
To aid designers of GaN power amplifiers (PA), Wolfspeed has selected several recent articles published by Microwave Journal, creating this handy eBook reference. We begin with a survey of the RF GaN market written by the consulting firm Yole Développement. “The RF GaN Device Market: A Roller-Coaster Ride.” Then “A Dive into Integrated PA Topologies for 5G mMIMO,” written by Wolfspeed, discusses the benefit of using GaN rather than LDMOS and how best to design the GaN PA. The article “Broadband, High Efficiency, Class J Power Amplifier Design Method with Compensating Drain-Source Capacitance,” written by authors from Hangzhou University and the University of Kent, describes a single-ended GaN PA design covering the cellular bands from 1.4 to 3.6 GHz that achieves approximately 10 W output power, between 60 and 68 percent drain efficiency and an adjacent channel power ratio better than −30 dBc. The next article, “Doherty Power Amplifiers Move to mmWave,” written by PRFI, describes the design of an asymmetric Doherty PA MMIC for the 28 GHz 5G band. The design was processed using Wolfspeed’s 0.15 μm GaN on SiC foundry process. The next article, “The Maximally Efficient Amplifier,” written by Rohde & Schwarz, explores the theoretical circuit approaches for maximizing a PA’s efficiency: waveform engineering, supply modulation and load modulation. The eBook concludes with “Choosing the Right Signal Source for Reliable Measurements,” a cautionary reminder from Rohde & Schwarz that the quality of the signal source causes measurement uncertainty and error.
Antenna tuners in smartphones, like other electronic components, must be able to withstand electrostatic discharge (ESD) at every stage from device manufacturing and smartphone assembly to consumer use. Rather than rely on legacy assumptions, tuner selection should reflect the manufacturing systems and standards of today. Learn more to protect your devices.
5G is now and what’s next? As a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030. Download this white paper to explore the evolution from 5G to 6G from a service, air interface and network perspective.
This article will introduce the three trends driving the need for persistent spectrum monitoring before comparing the benefits of a proactive approach to traditional RF drive tests which are often reactive and capture only a brief snapshot of the wireless environment. It will conclude by highlighting some of the key features and performance requirements RF Engineers should consider when comparing RF receivers.
Remcom’s XFdtd® Electromagnetic Simulation Software contains analysis tools for rapidly characterizing the performance of arrays of antennas for beamforming and beam steering applications. This whitepaper demonstrates how unique features like superposition and array optimization simplify the process for understanding device performance by providing efficient ways to validate array coverage.
