  • Introduction to RF/Microwave Launch Accessories & Field Replaceable Connectors

    06/02/2022

    Many RF/microwave applications use connectorized modules that are hermetically or otherwise sealed to protect sensitive internal electronics from the elements. In some rugged applications, such as military, aerospace, industrial, and telecommunications, the exposed connectors on these modules can become corroded or otherwise damaged during regular use. This is especially true if the external connectors are ..

    More on ISM Bands Around the World

    12/16/2021

    Though not likely the original intent of the creators of the industrial, scientific, and medical (ISM) radio frequency bands commonly accepted throughout the world, much of the modern ISM bands usage is now low-power wireless communications. A large portion of Internet-of-Things (IoT) technology is reliant on “unlicensed” but not “unregulated” ISM bands. This is an ..

    What is a Dielectric Resonator Antenna?

    12/02/2021

    Dielectric Resonator Antennas (DRAs) are antennas formed from resonant dielectric radiators fed by a conductor carrying an RF signal. In this way, DRAs convert unguided waves transmitted by conductors to guided waves that are then emitted from the dielectric structure. As DRAs transmit through a dielectric there are no conductor losses and the potential for ..

    Dielectrics at High Frequencies

    11/18/2021

    Dielectrics are one of the three main categories of electrical materials, the other two being conductors and semiconductors. Common dielectrics used in electronic systems are ceramics, glasses, gemstones, and polymers. Dielectrics, or insulators, are described as being very poor electrical conductors, and unlike conductors, allow for electrical fields to pass through them. However, the electric fields ..

    Role of Analog-to-Digital (ADC) Converters in Spectrum Analyzers

    11/04/2021

    Analog-to-digital converters (ADCs) are the backbone of virtually all modern test and measurement equipment. These devices are responsible for converting the real-world RF signals to digital signals that can then be further processed/stored and displayed to the user. There have been significant advances in ADC technology in recent years, with much faster ADCs with higher ..

    Key Spectrum/Signal Analysis Settings

    10/21/2021

    There are a wide variety of Signal/Spectrum Analyzers on the market that use a wide range of methods and technologies. Most modern spectrum analyzers use Analog-to-Digital Converters (ADCs) to convert the time-domain signals input at the port of the spectrum analyzer to frequency domain data using Fast Fourier Transforms (FFTs). Some spectrum analyzers, typically those ..

    Uses for Matching Pads

    10/07/2021

    The terms Impedance Matching Pads, resistive impedance transformers, or minimum loss pads all refer to the same RF components that solve a relatively common problem in some applications that have equipment, components, and devices at different standard impedances. For example, many broadcast, TV, and military communication systems use 75 ohms as a standard characteristic impedance, ..

    What Makes a Hi-Rel Amplifier Hi-Rel?

    09/23/2021

    The main application for High Reliability (Hi-Rel) RF/microwave amplifiers is for military, defense, aerospace, and other critical applications where device reliability is otherwise mission critical. In essence, a Hi-Rel Amplifier is just an amplifier that meets one or more military standards for reliability. In order to ensure device and system reliability, the US military developed ..

    All About Waveguide Shorts and Shims

    09/09/2021

    For many RF test applications in the higher frequencies, such as millimeter-waves, or for high power use cases, rectangular waveguides are the interconnect solution of choice. In a similar wave to short-open-load-through (SOLT) calibration standards used for vector network analyzer (VNA) calibration with coaxial interconnect, VNA using waveguide interconnect requires waveguide calibration standards. Even with ..
