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 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 ..

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 ..

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 ..

Increasingly, mini coax cable connectors play a crucial role in modern electronic systems, offering compact solutions for high-frequency signal transmission in tight spaces. Designed for efficiency, mini coax cable connectors excel in applications where size and weight are key considerations, including telecommunications, medical equipment, and automotive electronics. They enable seamless communication between components, maintaining signal ..

When it comes to installing or repairing coaxial cables, one of the most important tools is the RG 6 crimping tool. The RG 6 crimping tool is a specialized tool designed to create strong, secure connections between RG 6 coaxial cables and their connectors.  Whether you’re a seasoned professional or new to repair and installs, ..

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, ..

In the realm of high-frequency signal transmission, the choice of connectors is crucial for maintaining signal integrity and overall system performance. One connector that stands out for applications up to 40 GHz is the 2.92mm connector, commonly known as the K connector. This blog post delves into what the 2.92mm connector is, where it’s used, ..

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 ..

In today’s world of fast-paced communication, micro wave antennas play a crucial role in microwave communication systems. These antennas are essential for transmitting and receiving electromagnetic waves at microwave frequencies, typically ranging from 1 GHz to 100 GHz. In this blog post, we’ll dive into what micro wave antennas are, how they work, and explore ..
