  2. Field Probe Correction Factors 7/14/2020

    To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.

  3. The Week in 5G: 7/7/2020 — 3GPP Release 16 Ratified; U.S. Continues Hunt For 5G Spectrum 7/7/2020

  4. Understanding edgeBoost™, bandBoost™ and coexBoost™ – Three Types Of Wi-Fi Filters 7/1/2020

    While it may generally be thought that “a filter is a filter,” there are actually many different filters that solve different problems for different types of use cases, and with different benefits. In general, of course, the purpose is to improve the quality of data communications. However, before making any decisions about including filters in your design, it might be good to understand what specific effect is desired. This paper addresses what types of filters are used and for what purposes.

  6. Qorvo Biotechnologies Sensor-Based Technology Provides Rapid Reference-Lab Quality Tests At Point-of-Care 6/29/2020

    This white paper describes Qorvo Biotechnologies’ Bulk Acoustic Wave (BAW) immunosensor detection platform designed for point-of-care applications and describes analytical and functional sensitivity testing on human Thyroid Stimulating Hormone (hTSH) as an example. The Qorvo Biotechnologies’ platform is targeted to be central lab matched, with the goal of providing clinicians data that will enable quicker decision making across multiple disease states, such as in cardiac and infectious disease segments, where time to result and high performance are critical factors in the patient care workflow.

  7. Transforming The Retail Experience – Top Four RF Opportunities 6/29/2020

    The global coronavirus crisis is placing unprecedented pressure on the retail industry. Brick-and-mortar retail spaces, like grocery stores and pharmacies, have new protocols to keep customers and employees safe. Retail is not just seeing a drop in demand. The coronavirus has also triggered a shift in consumer behavior as more spending moves from physical stores to online, even for products that people traditionally bought “offline.” While it’s unknown how consumer behavior will adapt, retailers will likely accelerate the integration of their online and offline presence if they haven’t already. They will also double down on investment in Smart Retail solutions that strengthen their position amid this transformation of retail.

  9. Mitigate Spectrum Challenges Associated With V2X 6/19/2020

    Wi-Fi and 5G are enablers of autonomous vehicles. The challenge lies in how these technologies work together and co-exist - without impacting vehicle operation and passenger safety. This paper discusses Wi-Fi and 5G, how they co-exist with high-selectivity filter solutions to enable vehicular communications and passenger safety.

  10. Ka-Band Satcom Trends And Power Amplification Challenges 6/19/2020

    The ever-expanding appetite for data is driving strong growth in satellite communications (satcom), especially in higher-frequency bands. But, instead of concentrating on the lower frequency ranges, many companies are focusing on higher frequency Ka-Band, which provides more allocated spectrum for applications such as internet access and 5G.

    Operating in Ka-band creates new challenges in RF power amplification due to an increase in video bandwidth requirements and the need for high linear power to support multi-carrier systems. Thanks to advances in semiconductor technology, GaN PAs have increased performance and are now an attractive alternative to high power vacuum tube amplifiers. This article provides insights into current satcom trends and approaches to Ka-Band power amplification.
