Why Hermetically Seal RF Adapters and how is it done? RF coaxial adapters are often the difference between expensive options of reordering RF cable assemblies, RF connectors, or even retrofitting RF assemblies with new RF coaxial connectors, and a few seconds of installing a quick fix. Also, RF adapters are useful in protecting/extending the life of the RF...

The Wide and Diverse World of RF Antennas 900 MHz Patch Antenna Electromagnetic (EM) Antennas are an essential component for virtually all transmission and reception systems that operate in the RF, microwave, millimeter-wave (mmW), and terahertz (THz) frequency ranges. Another way to look at EM Antennas, is that these antennas can be designed to convert conducted EM...

Low-PIM, Low-loss, and Phase-Stable Cable Assembly Application Considerations Coaxial cables are arguably the most common RF/microwave physical interconnect technology. Outside of waveguides and planar interconnect, coaxial cable assemblies are one of the few proven methods of reliably connecting RF/microwave/millimeter-wave networks. Given the diverse range of applications for coaxial cable assemblies, these cables are not one-size-fits-all. There are a...

Bidirectional Amplifier Basics By: Steve Bowman 06/23/2022 A Bidirectional Amplifier, or Bi-directional Amplifier (bda), is an active RF device that is widely used in a variety of telecommunication, radar, and other RF sensing applications. Though conceptually a Bidirectional Amplifier performs a relatively simple operation, the internal electronics can be somewhat complex. Moreover, many applications favor certain names and types...

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...
