MICROWAVE ENGINEERING
- 1. Microwaves have large band widths compared to common bands
- 2. Fading effect due to variation in the transmission medium is more effective at low frequencies
- 3. EM waves are oscillations that propagate through free space
- 4. The TEM waves are propagated equally in all directions if the source is a point source
- 5. Series junction is also known as E-Plane TEE
- 6. The spherical TEM wave is known as a plane wave
- 7. Electric and Magnetic fields are purely transverse to the direction of propagation
- 8. Transmission lines can also be used as Circuit Elements
- 9. The magnitude of standing wave can be measured interms of Standing Wave Ratio
- 10. The TWT is an O-Type device
- 11. The magnetron is a self contained Microwave Oscillator
- 12. IMPATT is an abbreviation form of Impact Ionization Avalanche Transit Time
- 13. Two modes of negative resistance devices are Voltage Controlled Mode and Current Controlled Mode
- 14. Bolometer is also known as Square Law Device
- 15. In low VSWR measurement, value of VSWR is less than 10
