Slide screw tuner precision micrometer type It is used to match loads, detectors, or antennas to the characteristic impedance of the waveguide. The combination of the depth and the position of the probe causes reflection in the wave guide at a specific amplitude and phase. Microwave test bench MWB05 10. Wave guide Stands They are used to support the microwave components for setting up waveguide Test bench. 11. Shorting plate When measuring the wavelength inside of a wave guide. a shorting plate is used to create a short (zero impedance) at the open end of a wave-guide. 12. Fixed attenuator. The purpose of the fixed attenuator is to provide a fixed attenuation, isolation, padding etc. The attenuation is obtained by insertion of a thin conducting absorber into a straight portion of a standard waveguide. Attenuation 3dB 13. Magic-Tee (or Hybrid-Tee) A magic-Tee is a four port device where power incident on any arm splits equally between the two adjacent arms, but there is no power coupled to the opposite arm. The magic-Tee is an essential device in balanced mixers, automatic frequency control circuits and Impedance measurement circuits. 14.
