  1. The Future Of IoT Will Require LTE Connectivity
    5/22/2019

    As the promise of a wirelessly connected world becomes a reality, there is a growing need for LTE technologies that address low cost, long battery life, security, and reduced complexity — all critical components for IoT.

  2. Introduction To Qorvo’s 100 MHz ET For 5G
    5/22/2019

    With the rise in handset RF complexity, envelope tracking (ET) has become the optimal choice for RF power amplification in mobile handsets. This application note discusses Qorvo’s 100 MHz envelope tracking integrated circuit (ETIC) for 5G applications.

  3. Introduction To Specifying RF/Microwave Power Amplifiers For EMC Testing
    5/17/2019

    Historically, amplifier selection for Electromagnetic Compatibility (EMC) testing was based mainly on tribal knowledge and information scattered across the EMC industry. This application note provides the EMC test engineer or technician with the information necessary to make the proper decision.

  4. IoT Standards: The End Game
    5/15/2019

    It can be confusing to try to pick standards while waiting for 5G or NB-IoT deployments. This article answers the question of which standards are best to use and looks ahead at the future of wireless technologies to help gain a better perspective as to where things are headed.

  5. How Big Is A Wavelength?
    5/13/2019

    In traditional arrays an inter element spacing of less than half the wavelength (<λ><λ/2) is required to mitigate grating lobes. To understand the shift in system design this brings about, this paper looks at the physical scale of different wavelengths compared to some familiar references.

  6. Control Your Amplifier Remotely: ampwebwARe Software
    5/13/2019

    While RF and microwave amplifiers themselves may never become truly ‘mobile’, the way we control them can be.  AR’s new ampwebwARe gives you the capability to monitor and control your amplifier remotely without needing any software of your own. 

  7. A 5G, 60 GHz Antenna Array For Use With mmWave Wireless Virtual Reality Headsets
    5/13/2019

    This example demonstrates an antenna array for 5G 60 GHz applications of wireless communication for wearable devices such as virtual reality headsets. The antenna design for this example is from the paper by Hong and Choi of Hanyang University. The array is composed of four elements which each have two patches and a parasitic element. The parasitic element aids in producing a wider beam in one dimension to give better coverage. The beams may be steered by varying the phase shift between elements to provide near hemispherical coverage.

  8. Skyworks Medical Solutions
    5/10/2019

    When reliability counts, Skyworks delivers. Vital medical equipment such as patient monitors and scanners rely on solutions from Skyworks to ensure two-way communication.

  9. How GaN Is Changing The Satcom RF Front-End
    5/9/2019

    In the past, traveling wave tube amplifier (TWTA) and gallium arsenide (GaAs) were the go-to RFFE technologies for power amplification in satcom. Now, GaN and GaAs semiconductor technologies are becoming the go-to solutions; GaN has been replacing TWTAs due to its high-power performance and reliability combined with a small form factor. GaN and GaAs are enabling a wide variety of commercial and military satcom applications, such as 5G backhaul, ultra-HD TV transmission, satcom-on-the-move, internet access for aircraft passengers, and manpack terminals.
