Microwave trainer

MW-E/EV

This Microwave Trainer is designed to study and test lines and antennas used to broadcast information in microwave field.
In detail, it is possible to analyse and test the following major aspects related to microwaves and to their application in communication systems.

  • Microwave generation with Gunn oscillator
  • Waveguide Components and Antennas for microwaves
  • Assembling and Measurements

This unit consists of a main Trainer and of a set of optional waveguide Components (WG).

Training program

  • General microwave theory
  • Characteristics of:
    • Microwave components
    • Waveguide and flange
    • Horn antennas and parabolic reflector
    • Reflection and polarization system
  • Gunn Diode oscillator
  • Gunn transceiver: Gunn oscillator and Schottky diode
  • Measurement of direct frequency (with opt. Mod. MW-E1/EV)
  • Wavelength measurement: in free space and WG
  • Measurement of direct and reflected power
  • Attenuation measurement
  • Power division and impedance mismatching measurement (with opt. Mod MW-E2/EV) SWR and impedance matching measurement.
  • Use of Smith’s chart for impedance calculation
  • Impedance matching (with opt. Mod MW-E3/EV)
  • Signals separation in a transceiver system and transmitter protection (with opt. Mod MW-E4/EV)
  • Directional couplers and T-hybrid
  • Microwave antennas: gain and irradiation diagram
  • Measurement of antenna gain:
    • comparison method
    • method of the two antennas
  • Link attenuation
  • Passive repeaters (mirrors)
  • Doppler Radar with different antennas: it is possible to observe the relationship between the object speed and the received doppler signal
