5EC8 MICROWAVE ENGINEERING LAB

1.  Study of various microwave components and instruments like frequency meter, attenuator, detector &

VSWR meter.

2.   Draw V-I characteristics of microwave source like Gunn diode/ Reflex Klystron.

3.  Measurement of frequency and wavelength in a rectangular waveguide.

4.  Measurement of VSWR (small as well as large values) & reflection coefficient.

5.   Measure an unknown impedance with smith chart.

6.   Draw the following characteristics of Gunn Diode

(i)  Output power and frequency as a function of voltage

(ii)  Square wave modulation by PIN diode.

7.  Drawing  polar pattern of Horn antenna.

8.  To observe the action of directional coupler and its use in separating incident & reflected wave.

9.  Study of Magic Tee, Circulator, isolator

10.  Study of spectrum analyzer & its use in observing the response of

(i)  High frequency amplifier

(ii)  Low pass, high pass, band pass, band reject filters.
