The dominant use of coaxial cable in RF & Microwave applications is as a transmission line. Coaxial cables are extremely useful transmission lines as the coaxial nature of the transmission line provides relatively efficient transmission from DC to a cut-off frequency, which is a function of the geometries of the coaxial components of the cable. ..

An Antenna Downtilt and Coverage Calculator, or Antenna Tilt Calculator, aids the user by providing an approximate downward angle at which to install a directional antenna to reach desired signal strength and coverage between a transmitter and receiver at different heights and some distance away. An example use case is when a cell-tower directional transceiver ..

RF Electromechanical Relay Switches, RF electromechanical switches, or RF electromechanical relays are a type of RF switch with mechanical contacts driven by electrically driven actuators. The transmission paths within an Electromechanical relay switch are purely passive, and thus exhibit relatively low loss and high isolation compared to active switch technologies. Due to the low loss ..

In an ideal RF system, all of the energy from the RF source is transferred to the load. An example of this would be a transmitter delivering a signal to an antenna with the interconnect between the two signal chain components operating at 100% efficiency. Clearly, this isn’t the case, and factors like impedance mismatch ..

When it comes to temperature conversions, switching between Celsius and Fahrenheit can be confusing. Whether you’re traveling, cooking, or working on science projects, knowing how to convert Celsius to Fahrenheit (or vice versa) is crucial. That’s where an instant C to F calculator comes in handy. In this article, we’ll walk you through everything you ..

  RF coaxial connectors are one of the most useful and ubiquitous methods of connecting RF systems and components. RF coaxial connectors are coaxial transmission lines made up of an RF coaxial cable and RF coaxial connectors terminating either end of the cable. RF connectors provide interconnect with other RF connectors, which must be of ..

The Pasternack The Cable Creator Tool™ is a powerful method of ordering custom coaxial cable, where all cable assemblies ordered through the tool are typically built and shipped the same day as ordered. The selection of connector types, cable types, and configurations are extremely diverse and should fill virtually any coaxial cable assembly need. The ..

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 ports of expensive to service and replace ..

At first look, there are many different types of RF amplifiers, and it could be overwhelming to go from the specs you need to narrowing down what RF amplifier type is the best fit. Most RF amplifier types came about from the specification requirements of common transceiver, receiver, transmitter, radar, and modulation circuits and system-level ..

Automated Test Equipment (ATE) are automated systems designed to perform electrical, thermal, and physical testing without the direct interference of a person. Usually ATE systems are employed to speed up testing, perform repetitive tasks, or to enhance the repeatability and consistency of a testing system. Often, an ATE system is designed to do all of ..
