  1. Where Is Wi-Fi Heading?
    11/20/2017

    What matters the most to the future of Wi-Fi technologies? Major concerns include high data rate, high capacity, and a good range of coverage. This white paper covers these areas of interest, the problems involved in implementing Wi-Fi growth requirements, and possible solutions.

  2. How Not To Run Hot: Overcoming Thermal Challenges In Wi-Fi Front End Designs (Part 1)
    11/20/2017

    It can be hard to fully account for thermal management and affected parameters in wireless access points or customer premises equipment prior to FCC certification. This article is the first in a series that looks at the design challenges for Wi-Fi front end designs. Part 2 will cover coexistence and interference.

  3. Smart Homes For Seniors: How The IoT Can Help Aging Parents Live At Home Longer
    8/23/2017

    The population of adults 85 and older in the U.S. will roughly triple between 2015 and 2060, making it the fastest-growing age group over this time period. This has become a major concern for families taking care of seniors who will be living on their own. Qorvo’s Senior Lifestyle System has been tested and used for the last 15 years in assisted living communities in Europe to help seniors live more independently. Within a few weeks, this system learns the routine day-to-day activities of the senior resident, provides intelligent status updates in a dashboard app, and sends alerts to designated caregivers if something unexpected happens.

    By monitoring behavior patterns through unobtrusive wireless sensors located around the home, the system is able to detect changes in behavior that may cause concern, and then alerts family members or caregivers via messages. 

  5. Designing A Broadband L-band 160 W GaN Power Amplifier Using SMT Packaged Transistors
    6/30/2017

    Advancements in Gallium Nitride technologies are leading to amplifier operation at higher powers, supply voltages, and frequencies. The whitepaper includes load-pull measurements, thermal considerations, and EM simulations of the input/output matching networks.

  6. A Better Way To Market Internet Of Things: Smart Home Butler
    6/30/2017

    The smart home revolution has taken a lot longer to get up and running due to the disagreements over what protocols and platforms should be used in the base technologies, as well as the poor choices in consumer words like “smart home” and “IoT.” 

  7. Utilizing GaN MMICs And Coaxial Waveguide Spatial Power Combining In Power Amplifiers
    5/16/2016

    Solid state amplifiers can be constructed through the use of MMIC amplifiers to reach output powers and performance levels that have only been achievable by traveling wave tube amplifiers (TWTAs). This white paper demonstrates building a 120 Watt power amplifier operating from 27 to 31 GHz.

  8. Carrier Aggregation In Mobile Devices
    2/10/2016

    Carrier aggregation (CA) enables mobile network operators worldwide to provide faster data, and allows mobile devices to communicate on multiple LTE bands simultaneously. This, however, creates the challenge of avoiding interference between the bands while keeping up good reception and battery life. Multiplexers are an excellent solution for CA combinations that use closely spaced bands since they provide isolation between and within bands, while allowing them to connect to the antenna at the same time. This white paper discusses the challenges of carrier aggregation, and the important benefits of using multiplexer solutions to solve them.

  9. The Wi-Fi Evolution
    9/26/2019

    If you are looking to buy a new wireless networking gear or a mobile device, you may be overwhelmed by too many choices and abbreviations. Since Wi-Fi was first released to consumers in 1997, its standards have been continually evolving – typically resulting in faster speeds and network/spectrum efficiency – and it can be difficult to keep track of new standards. This paper is meant to help you understand the basics of Wi-Fi standards, and provides and overview of the evolution of Wi-Fi technologies.

  10. Resolving Interference In A Crowded Wi-Fi Environment Using BAW Filters (Part 2)
    9/26/2019

    There are any number of strategies that consumers can try to fix interference problems with Wi-Fi in their homes, but as an RF engineer, how can you design a Wi-Fi access point that addresses the biggest interference issues from the outset?
