edgeBoost™, bandBoost™ and coexBoost™ – Three Types of Wi-Fi Filters

These days, Wi-Fi designs often include filters, but why and what types serve what purpose? In this paper by Qorvo, learn why it is important to understand how the Wi-Fi use case determines the type of filter to use in order to improve the quality of data communications.

Minimize Measurement Uncertainty for EIRP OTA Measurements

The R&S®NRPM-A90(D) brings an unprecedented level of accuracy to absolute OTA measurements at an extremely reduced total cost of ownership. Furthermore, the detailed specifications enable you to determine the measurement uncertainty also for corner cases. Learn more in our material.

ATE Strategy For mmWave Mass Market Production

The automated test and measurement (ATE) landscape is rapidly changing, progressing beyond the capabilities of traditional bench-top and most legacy ATE systems. Varying and diverse performance requirements, testing speeds and frequencies used by modern cellular architectures (5G), Internet-of-Things (IoT) devices, and the latest feature dense systems-on-chip/systems-inpackage (SoC/SiP) necessitate a different approach.

TRL Calibration of a VNA

Thru-Reflect-Line calibration has a number of advantages over the SOLT method often used in VNA calibration. For SOLT calibration, the standards must be accurately characterized. The opens and shorts might be characterized by electromagnetic simulation of the physical design or have associated one-port “data-base” files obtained by highly precise measurement.

NewSpace Terminal Testing Challenges and Considerations

Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals (Figure 1). Each link in the supply chain presents unique challenges for R&D, production and deployment for both the components and system development.

Putting Crystal Oscillators in Their Rightful Place

The paper reviews the qualities of high-performance crystal oscillators that make them the preferred solution over MEMS oscillators in applications where high-reliability under extreme conditions is not an option. 

An Interview with Analog Devices Discussing RF Electronics for Phased Array Applications

With the continued advancement of ICs for the wireless industry, semiconductor companies once known only as component providers are now able to offer complete system solutions. This month we interview Analog Devices, a company unique in the industry, combining high-speed data converters with an extensive RF, microwave, and power portfolio.

Fundamentals of Spectrum Analysis

The Rohde & Schwarz fundamentals are intended to familiarize the uninitiated reader with the field of spectrum analysis. To understand complex measuring instruments it is useful to know the theoretical background of spectrum analysis.

Extending the Performance and Frequency Envelope for QFN Packaging Technology

“High-performance, millimeter-wave MMIC products” and “cost-effective surface mount lead-frame-based packaging” typically don’t come up in the same conversation, and for good reason. Just two or three years ago, it was difficult to conceive of operating at frequencies above 20 GHz without considering an expensive, open cavity, HTCC package or resorting to more bespoke chip and wire assemblies.

Verifying RF Device Performance With a Blocking Test

The increasing density of devices, machines, systems and vehicles using wireless connectivity solutions can pose a great challenge for a new Wi-Fi module due to the presence of interfering signals. A wireless receiver’s ability to receive a wanted signal in the presence of an interfering signal is described by blocking characteristics.
