  • Radar Absorbers
    narrowband in frequency implies narrowband in angle. Broadband behavior requires grading the properties from light on top to heavy on the bottom. Wideband behavior can be obtained by using transformer/filter design concepts – a combination of interference and absorption. Most absorbers are backed
  • A High Power Solid State T-R Switch
    connected PIN diode between the. antenna and transmitter and an additional one between the antenna and. receiver. This configuration is shown in figure 1. Figure 1. Broadband Transmit-Receive Switch Design. This SPDT switch is operated by supplying forward current to the arm where low. insertion loss
  • Theory and Application of RF/Microwave Absorbers
    performance. Multiple discrete. layers can be stacked which will enable the 377 ohm input impedance condition over. a broader range of frequencies. The design of this class of material is similar to de-. sign for a quarter wave transformer. Impedance gradient. A second class of broadband absorbers uses
  • Understanding In-Line RF Power Measurements
    plasma application may be quite different from that of driving a broadband, resistive dummy load. To be of any diagnostic value, attempts to monitor or verify energy delivery performance through the use of externally applied in-line wattmeters requires an understanding of the measurement type and also
  • Basic Antenna Terms and Definitions
    Factor (AF) is defined as the ratio of the incident Electromagnetic Field to the output voltage from the antenna. Balun: An acronym for Balanced/Unbalanced. Typically an RF transformer used to couple a balanced transmision line to an unbalanced antenna system. Beamwidth: Depending on the radio system
