  1. Introduction To Vector Network Analyzers (VNAs)

    Vector network analyzers (VNAs) are used for the validations of design simulations in a wide range of RF and high frequency applications. In manufacturing applications, RF components ad devices are assembled and tested based on a certain set of specifications. VNAs are often used to quickly and accurately validate the performance of these RF components and devices. This white paper discusses the basics of VNAs, how they are unique compared to other RF test equipment, and best practices for their use in a variety of measurements.

  2. Implementing A Flexible Testbed For 5G Waveform Generation And Analysis

    This white paper discusses candidate waveforms for 5G research and introduces a new flexible testbed for 5G waveform generation and analysis. This testbed combines software solutions with test equipment to investigate and to perform “what-if” scenarios for new emerging 5G waveform applications. Co-existence scenarios between candidate 5G and 4G waveforms are also investigated.

  3. System Simulation Primer For RF Link Budget Analysis

    An RF link budget is used to account for all the gains and losses in a telecommunication system. By accounting for the attenuation of the transmitted signal as it propagates through the communications channel, system designers can determine the required signal strength and antenna gain necessary to overcome all feedline and miscellaneous losses and to ensure an appropriate quality of signal for successful data transmission.

  4. The Future Is Now: Technology And Future Soldier Systems

    Many modern technological possibilities are available thanks to the evolution of sensor technologies and wireless devices. Likewise, the equipment and gear that a soldier needs have evolved to provide enhanced communication, detection, protection, real time situational awareness, and data analysis. In this article, new technologies and the future of soldier systems – such as segmented reality equipment – is discussed.

  5. 5G Primer For MIMO/Phased-Array Antennas

    5G is driving many of the requirements for products today and pushing for the enhancement of over-the-air (OTA) efficiency with the expansion of multiple-in-multiple-out (MIMO) and beam-steering antenna technologies. As 5G pushes into these higher frequencies, beam-steering antennas will be required to direct radiated energy from the base station antenna array to the end user, while overcoming the higher path losses that occur at these frequencies. This application note primer examines some of the simulation technologies available that support the design of MIMO and beam-steering phased-array antennas.

  6. The Future Of EMC Test Laboratory Capabilities

    The complexity of modern day electronics has resulted in the need for better EMI diagnostic capabilities at EMC test laboratories to combat the increase in EMI compliance failure rates. One solution is to use real-time mode which enables visualization of the spectrum to provide insight in the identification of the source of failing EMI emissions. This white paper describes the cause of the shift in failure rate that many companies are experiencing, the need for increased speed in testing, and the revolutionary EMI diagnostic capability built into modern EMI receivers.

  7. Linearity Measurements On RFFE Components

    Components in the RFFE (radio frequency front end) cause distortions that limit the performance and throughput in communications systems. This application note demonstrates a number of individual RFFE component and complete RFFE linearity measurements used to characterize the distortions of these components.

  8. Role Call: Senior Staff Packaging Engineer

    Role Call, a series on RF Globalnet, takes a “peek behind the curtain” to help answer the questions related to different jobs and career paths in the RF and microwave industry.  Recently, Mumtaz Bora, Senior Staff Packaging Engineer at pSemi, took time to answer some questions about her occupation.

  9. Utilizing A Wideband Receiver For 5G, Instrumentation, And ADEF

    The limitation of bandwidth is one of the biggest challenges for radio designers, especially when designing analog-to-digital converters (ADCs) where high fidelity is required, such as in 5g, instrumentation, and ADEF applications. This application note discusses the use of the AD9213 ADC for these applications, its benefits, and how it creates new options for direct sampling wideband systems.

  10. Understanding Robust Wireless Communications For Industry 4.0

    The Smart Industry, or Industry 4.0 is the new industrial revolution where existing systems are networked together to create cyber-physical systems. Industry 4.0 is built on a reliable communications infrastructure enabling data extraction from machines, factories, and field devices to be sent to the cloud for aggregation and processing. For good connectivity in these industrial ecosystems, reliable radio connections are critical, yet challenging. This white paper discusses the importance of creating reliable wireless communications systems for Industry 4.0, and offers considerations for improving network coverage.
