  1. Small Cell Networks And The Evolution Of 5G: Part 1

    This article is the first part in a two-part series on the topic of small cell base stations. Part 1 covers the basics of small cells and how they fit into the evolution of 4G and 5G.

  2. Power Class 2: What You Need To Know

    RF engineers are continually challenged when designing RF front-ends for mobile devices. Not only do they have to deal with balancing multiple frequency bands, fewer SKUs, and difficult coexistence requirements, another LTE power standard has emerged to further complicate the RF front-end design for mobile handsets.Qorvo’s blog article offers advice on meeting the new Power Class 2 standard.

  3. RF Architecture Choices For Next-Generation Handset Designs

    Today’s smartphone market has expanded into several categories with differing design goals and priorities, which require different approaches to RF front end (RFFE) integration. Modern packaging techniques make it possible to combine multiple RFFE components into integrated modules which help smartphone manufacturers accelerate the design and manufacture of new handsets. However, since there are two key smartphone categories – flagship phones and mid-tier and entry-level handsets – it raises the question of what would be the right level of RFFE integration and the best integration approach for each one?

  4. Addressing Carrier Aggregation Challenges Using Multiplexer Solutions

    How do operators avoid interference between bands while minimizing insertion loss? Multiplexers. They are designed to integrate the required filters for multiple aggregate bands, provide isolation within and between the bands, and allow them to simultaneously connect to the antenna. 

  5. Advanced RF Filters For V2V And Other Automotive Applications

    This white paper discusses three key filtering challenges addressed by BAW filter technology: 802.11p in the DSRC band, LTE-Wi-Fi coexistence, and satellite radio. It also examines reliability and temperature stability considerations specific to automotive use. 

  6. Gallium Nitride — A Critical Technology For 5G

    In addition to being “greener,", 5G has goals of 1 ms latency, 100 x network energy efficiency, 20 Gbps peak data rates, and 10 Mps/m2 area traffic capabilities. This article discusses how RF Gallium Nitride (GaN) technology can be used for emerging 5G technologies.

  7. What Is The Real Value Of IoT?

    The name “Internet of Things” (IoT) can be misleading in that it does not actually refer to a specific group of things. It really isn’t a new concept either, rather a maturing technology that is making its way into the mainstream eye. Just like every other universally connected device, it operates over our regular internet with familiar applications in wearables and the smart home. So what is the real value of IoT? This white paper provides information on what the IoT has to offer now and in the future, and what defines its true value.

  8. What Is SHaaS? And Why Should You Care?

    Comcast released the results of a survey from earlier this year providing valuable insights into why consumers are interested in smart home services, what features are most desired, and how they plan to use smart home technologies. The biggest find of the survey is that consumers are more interested in a smart home as a service (SHaaS) over connected devices that remotely control devices in the home. This application note discusses SHaaS, its components, and how it works.

  9. Energy Efficiency In The Telecommunications Network

    The telecommunications sector accounts for roughly 4 percent of the global electricity consumption. However, the sector is actively participating in efforts to reduce energy use – both for economic reasons, such as reducing operating expenses, and for environmental reasons.

  10. CW Operation Of QFN-Packaged Pulsed GaN Power Amplifiers

    Improvements have been made to GaN amplifiers at microwave frequencies that have increased their generated output power levels while also shrinking the size of the system. These developments, however, present the challenge of providing sufficient thermal management. This Qorvo® application note discusses the thermal issues involved with using high-powered, small packaged (e.g. QFN) GaN amplifiers within high power CW systems. Download the full paper for considerations on component mounting in order to provide a low thermal impedance path to the system heat sink for optimum operation and reliability, using the TGA2307-SM as an example.
