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

More on ISM Bands Around the World By: Peter McNeil 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...

What is a Dielectric Resonator Antenna? By: Peter McNeil 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...

Uses for Matching Pads 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...

What Makes a Hi-Rel Amplifier Hi-Rel? 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...

All About Waveguide Shorts and Shims 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...
