  1. 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.

    Qorvo offers a range of RF connectivity solutions to help make 5G deployment a reality. These RF components provide flexibility to system designers, as well as the highest level of integration of multifunction building blocks to reduce size, lower costs, and accelerate time to market.

  3. Connectivity Q&A: Wi-Fi Pushes The Possibilities For Our New Virtual World 12/10/2020

    The COVID-19 pandemic is a worldwide phenomenon that has affected our lives in a multitude of ways. Most notably are the periodic stay-at-home orders around the world that have shifted the way we regularly connect. According to research firm TeleGeography, in 2020, average international internet traffic increased 48%, while peak traffic rose 47%. Whether these numbers will return to pre-COVID values, or if this is the new normal, will remain to be seen. Tony Testa explores this new virtual landscape and offers some Wi-Fi specific insight into how manufacturers like Qorvo will develop solutions to help everyone adapt.

  4. Through The 5G Antenna Design Maze With Antenna-Plexers 11/19/2020

    Antenna-plexers provide a solution for how to accommodate the dramatic increase in RF complexity, even as the space allocated to antennas continues to shrink. They enable manufacturers to accommodate new 5G bands, 4x4 MIMO, and other new requirements with fewer antennas, and with no impact on existing form factors or features. By using antenna-plexers, manufacturers can deliver the full benefits of 5G without impacting their ability to add innovative features that attract consumers.

  5. Advanced BAW Filter Technology And Its Impact On 5G 11/19/2020

    The global rollout of 5G and rapid expansion of the IoT create significant RF filtering challenges. Bulk acoustic wave (BAW) filter technology is evolving to support higher frequencies and increased bandwidth for the new 5G and Wi-Fi band expansion. 

  6. Connectivity Q&A: The Mesh Network And The Advancement Of IoT Devices 11/18/2020

    Wireless connectivity has become one with the Internet of Things (IoT). The International Data Corporation (IDC) estimates there will be 41.6 billion connected IoT devices, or “things,” generating 79.4 zettabytes of data in 2025. Mesh networking will be a key mechanism to enabling this large amount of data for IoT devices in homes, cities, and businesses. Tony Testa provides some insight into how this all meshes in our world and how Qorvo plays an active part.

  7. Quick Guide To High Voltage Impedance Tuning 11/17/2020

    Antenna designers face a multitude of challenges with mobile handsets: the ever-increasing band coverage requirements, challenging industry design constraints, and the continually shrinking amount of real estate left to fit antennas. By using aperture and impedance tuners, designers can tackle these issues. However, not just any aperture or impedance tuner can be used. Many applications today require a more robust, reliable tuning product to fully meet design needs.

  8. Connectivity Q&A: IoT Networks Standards Explained 11/17/2020

    The term Internet of Things (IoT) has been in the news for several years now, but today we are seeing large adoption rates with the help of wireless lightbulbs, communicating Echo dots, connected thermostats, front door locks, doorbells, etc. The market company Statista is projecting 75.44 billion IoT devices worldwide by 2025 – a fivefold increase over a ten-year period. Applications span across all industries, including Industry 4.0, otherwise known as Industrial Internet of Things (IIoT). In this article, Tony Testa will provide insight into the IoT landscape, outlining the way in which this market fits and communicates in the wireless world around us.

  10. Mobile 5G Device Antenna Tuning Demystified 10/13/2020

    5G is bringing a significant increase in new bands that mobile antennas must support. More than ever before, there’s a need for handset designers to use more aperture tuners on a single antenna due to the complexity of the new phone designs. While each addition of an aperture tuner helps optimize the overall antenna performance for each band, it sometimes comes at the cost of antenna efficiency. Without the proper balance of antenna efficiency and performance of each band on an antenna, the overall device performance and range will suffer.
