  • Why Quality is Imperative for High Frequency Waveguides

    02/23/2017

    The quality of the construction and materials used can have a large impact on the performance of a waveguide system, especially in microwave frequencies and high power applications. This can become difficult to manufacture and evaluate, as the waveguide tolerances are extremely small at microwave and millimeter-wave frequencies. For instance, with millimeter-wave components and interconnects, ..

    Anatomy of a Coax Cable –and how they Work

    02/16/2017

    Coaxial cables are commonly known for being a broadband, relatively low-loss and high isolation transmission line technology. A coaxial cable is comprised of two concentric conductive cylinders separated by a dielectric spacer. The capacitance and inductance distributed along the coaxial line creates distributed impedance throughout the structure, known as characteristic impedance. The distributed resistive losses ..

    Antenna Gain and Directivity – The Basics

    02/09/2017

    What is antenna gain and directivity? Antennas, in essence, channel electrical power into electromagnetic signals. The shape, size, and connectorization all affect the antenna radiation pattern. Two key parameters in assessing the performance of an antenna are directivity and gain―directivity is a measurement of the concentration radiation in a direction while gain represents the power ..

    Directional Coupler and Power Divider/Combiner Overview

    02/02/2017

    Directional couplers are four port passive devices that employ an input port, output port, a port for the coupled signal and a port that is terminated internally. Directional couplers are used to couple a specific proportion of the power traveling in one transmission line out through another connection or port. Directional couplers are used in ..
