Description of the Microwave Communication Lab


The microwave and communications lab presently serves to give the ECE students a laboratory experience in basic electronic communications systems, microwave communication and optical communication. This lab is utilized for conducting the following courses.                                      

·16EC259 Analog and Digital Communication Lab

·16EC261 Microwave and Optical Communication Lab

The analog and digital communication lab is well equipped with oscilloscopes, signal generators, dual regulated power supplies, highly advanced arbitrary function generator, digital storage oscilloscopes, spectrum analyzers, Amplitude modulation and demodulation trainer  kit, Frequency modulation and demodulation trainer kit, Digital Communication trainer kits such as ASK,PSK, FSK, QPSK, Delta modulation. The training and experience that ECE students gain in this laboratory enhance their understanding of analog and digital communication systems.

The Microwave and Optical Communication Lab provides the student with an experience on analyzing the characteristics of microwave components and the various fiber optical communication techniques. The experiments conducted include S-parameter measurements, radiation and terminal properties of horn, slot, array, reflector, strip and patch and basic microwave measurements, such as gain in dB, impedance, power, frequency, VSWR, etc., using waveguide technology. The laboratory is adequately equipped with microwave benches at J-band and X-band, which includes Klystron tubes, Gunn diodes, Klystron power supplies, modulators, directional couplers, horn, slot, array, reflector, strip and patch antennas, various power energy ,VSWR meters and fiber optic trainer kits to enable the study of components of an optical communication system. The students perform optical communication experiments to study the characteristics of optical sources (LED & LD), measurement of numerical aperture, eye pattern, attenuation in optical link and data communication using optical link.

The laboratory helps students to

  • Analyze various parameters of microwave devices by constructing a microwave bench
  • Analyze and verify the characteristics of Reflex klystron, Gunn diode, Directional 
    coupler, horn antenna, Circulator and Isolator.
  • Calculate the numerical aperture, losses in fibers and analyze the characteristics of
  • LED, LASER sources and PIN detector experimentally
  • Construct and demonstrate the analog and digital modulation & demodulation
  • Construct and demonstrate the pulse code modulation and delta modulation techniques
