This eBook explores several topics relevant to radar performance, beginning with an article describing a radar architecture enabled by improved processing: the “holographic” or staring radar. The second article discusses how the performance of radars with complex waveforms can be assessed using sophisticated power measurement to characterize pulse operation and using noise signals with statistical power measurement to identify nonlinearities in the signal chain. Moving to the benefits of GaN on radar performance, Qorvo describes how increasing the operating voltage to 65 V increases device power density and power-added efficiency, to 9 W/mm and 80 percent, respectively. A second article from Qorvo compares the additive phase noise of linear and saturated amplifiers and between PHEMT and HBT processes. The eBook concludes with an interview with Dean White, director of Qorvo’s defense and aerospace segment, who shares his perspective of market needs and how Qorvo is aligning its process and product roadmaps to serve them.

There really is not a home for articles dealing with the challenges of the highest volume chips and their testing for high volume ATE. To serve this market, ATE companies, like industry microwave/millimeter wave instrument leader Teradyne, have developed instrumentation with features that create stability and repeatability at very high channel counts with reduced user complexity. But for this eBook, we did pull together some of the “best of MWJ articles” that talk about similar issues for you to whet your appetite including: • Navigating the 5G NR Standards, by Sheri DeTomasi, Keysight Technologies • Challenges for Effective and Realistic 5G OTA Testing, by Miguel Á. García-Fernández, EMITE Ingeniería S.L. and David A. Sánchez-Hernández, Universidad Politécnica de Cartagena • Significant Test Time Reduction and Equipment Utilization in 5G RF Production Testing, by Sascha Laumann, Rohde & Schwarz • The Phase Noise Challenge Pacing the Race to 5G, by Bill Linstrom, Ron Parrott and Allen Sweet, VIDA Products • Evaluating PCB Plated Through Holes for 5G Applications, by John Coonrod, Rogers Corp.

This white paper examines everything from lab-based testing and in-field performance testing to over-the-air (OTA) testing needs for vehicles. In the end, a clear overview of supplementary, non-communication related testing aspects in the automotive world is offered.

Understand the benefits of multi-probe technology for the faster testing and calibration of phased array antennas in LEO HTS, improving time-to-market and speed of production in the race to deliver viable connectivity on a global scale.

This application note belongs to a series of application notes which explain how to test EW receivers at RF in the lab with commercial, off-the-shelf signal generators and software. The series will cover all relevant use cases. This application note will discuss the generation of radar signals in a hardware in the loop (HIL) environment with PDW streaming.

As we witness the evolution of integrated communication, we also observe the increased number of requirements for airborne microwave transmission, ranging from satellite to air-to-ground CDL band communications. Airborne applications introduce many challenging design constraints including increased temperature ranges, thermal management, vibration and shock, EMC/EMI, power requirements, and safety, all while maintaining portability as a key factor.

Engineers often need to test the direction finding capabilities of radar warning receivers in the lab. A perfect solution is to use multiple coupled R&S®SMW200A vector signal generators that are phase-coherent and time-synchronized. This setup enables simulation of the angle of arrival (AoA) of radar signals in the lab.

In-car networks and advanced driver-assist systems (ADAS) present many design challenges to engineers. This white paper looks at Cadence® AWR Design Environment® software solutions for RF to millimeter-wave (mmWave) front-end component development that address electronic product development for automotive applications.

The articles in this eBook make the case for GaN for cellular applications. It begins with two views of the market trends and how these translate into forecasts, from Yole Développement and Strategy Analytics. Since efficiency is so important to power amplifiers, a foundational article by Rohde & Schwarz reviews the fundamental mechanisms that can improve PA efficiency: waveform engineering, supply modulation and load modulation. Illustrating waveform engineering, an article from researchers at Huazhong University of Science and Technology describe the design of a dual-band, continuous inverse class F PA. The following article examines the topology options for mMIMO PAs. Looking to the future, it concludes with an article describing development of a 28 GHz, ½ W linear, asymmetric Doherty PA MMIC.

Defining an automated test system can be challenging: the goal of a test system architect is to accelerate the test system design process, ensure that the system can be easily deployed and sustained throughout the product life cycle and, of course, all while maintaining test quality.
