  1. Combining Bluetooth And Low Power Cellular For IoT: Practical Design Considerations And Innovative Use Cases 5/22/2020

    This white paper’s goal is to help engineers successfully prepare for and execute their first cellular IoT design projects without needing to have the same level of expertise as a deeply specialized RF engineer, allowing the completion of projects with practical information and advice that product engineers can immediately put to use.

  2. RF/Microwave Design Software: Cadence AWR Design Environment, Version 15 5/21/2020

    The Version 15 (V15) release of Cadence® AWR Design Environment® software offers new and enhanced analyses through faster and higher-capacity simulation technologies, time-saving design automation, and 5G New Radio (NR) compliant testbenches. This article introduces the software and discusses the important changes and updates made to help with each design application.

  3. How Important Is mmWave To 5G? 5/20/2020

    For 5G to deliver high expectations, it must operate across wide contiguous frequency spectrum - only available at mmW frequencies. The frequency bands in the spectrum above 24 GHz can support large bandwidths and high data rates, ideal for increasing the capacity of wireless networks. Anokiwave offers the industry's most complete portfolio of Silicon ICs for mmW 5G and is the trusted choice of Tier-1 and -2 OEMs worldwide.

  4. Introduction To RNVNA, A Multiport Network Analysis Solution 5/20/2020

    In many RF applications it is necessary to make multiport measurements. The RNVNA, a multiport network analysis solution, links up to 16 1-Port analyzers together into a multiport network analysis system. Each of the 16 analyzers will make individual vector reflection measurements and scalar transmission measurements from port to port.

  5. An Introduction To Direction Finding Methodologies 5/18/2020

    All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

  6. The Rebirth Of HF 5/18/2020

    HF, or “high frequency” technology, usually refers to signals with frequencies in the 3 MHz to 30 MHz range, all though, many practical cases extend these frequencies as low as 1.5 MHz. One of the best-known applications of HF is worldwide or global communications. Government, military, and commercial broadcasters can reach listeners worldwide using HF frequencies. This paper explores the unique properties of HF that enable global communications.

  7. From The 1920s To The 2020s – Bandwidth Has Always Been King 5/15/2020

    Over time, the telephone replaced the telegraph, and now cellular and voice over Internet protocol (VoIP) technology are replacing the landline. As more communication is done wirelessly and over the Internet, we are becoming more interested in increased bandwidth. This is because bandwidth places a limit on how quickly we can send information through a channel such as an optical fiber or a section of the radio spectrum.

  8. Who’s Looking Out For Your Spectrum? 5/14/2020

    As the number of participants in communication systems increases, so does the noise level. To be heard, you either increase your volume, request them to repeat themselves or wait for a quiet period.  These basic principles form the building blocks of the wireless world we find ourselves in.

  9. The Advantages Of Using Computational Electromagnetics 5/14/2020

    Computational Electromagnetics (CEM) tools allow for highly complex scenarios (lightning effects, high-intensity radiated fields, cable cross talk, etc.) to be evaluated with a high degree of accuracy. This article discusses the advantages of CEM tools and common challenges of effectively incorporating them into simulations.

  10. Facing 5G NR Test Challenges 5/13/2020

    With initial 5G trials and deployments now using the official 3GPP standard,design laboratories and conformance test facilities are facing the struggle to deliver user equipment, fixed-wireless access (FWA), and customer premise equipment (CPE) verified to meet this standard, and also to anticipate the next steps in 5G technology, the 3GPP standard, and corresponding test requirements.
