  • SMA Connector Overview

    12/29/2022

    SMA Coaxial Connectors, or just SMAs, are one of the most common coaxial connector types used throughout the RF, microwave, and even millimeter-wave (mmW) industries. SMA stands for subminiature version A and was developed in the 1960s. The interface dimensions and other aspects of the SMA connector are detailed in MIL-STD-348 and was originally designed ..

    Coaxial Cable Assemblies for Rugged Outdoor Applications

    12/15/2022

    RF Coaxial Cable Assemblies are used in virtually all environments where wireless systems are deployed. Coaxial cable assemblies are integral internal parts of many wireless systems, and they are also used as interconnects between systems. These cable assemblies are often anywhere from a few inches long to hundreds of feet in length. This range of ..

    Power Added Efficiency (PAE) Calculator Explained

    12/01/2022

    RF power amplifiers typically have an input, output, and power supply rails. These rails can be either positive, negative, or dual positive and negative voltages. The input, output, and power supply rails all have recommended operating ranges of power, voltage, and current. This range is specified to nominal operation in what the manufacturer was able, ..

    Coaxial Cable Impedance Calculator

    11/03/2022

    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. ..

    Antenna Downtilt & Coverage Calculator Chart

    10/20/2022

    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 ..

    CW Power Capacity vs Frequency (Electromechanical Switches)

    10/06/2022

    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 ..

    VSWR, Return Loss, Insertion/Transmission loss vs. Transmission Power

    09/22/2022

    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 ..
