Waveguide Phase Shifters
Waveguide Phase Shifters Waveguide Phase Shifters: A phase shifter is a two-port component that provides a fixed or variable change in the phase of the traveling wave. An ideal phase shifter is lossless and…
Waveguide Attenuator
Waveguide Attenuator Waveguide Attenuator: An attenuator is a passive device that is used to reduce the strength or amplitude of a signal. At microwave frequencies, the attenuators were not only…
Waveguide Discontinuities
Waveguide Discontinuities Waveguide Discontinuities: Any interruption in the uniformity of a transmission line leads to impedance mismatch and is known as impedance discontinuity or waveguide discontinuities. In a waveguide system,…
Difference between Magnetron and Reflex Klystron
The basic difference between Magnetron and Reflex Klystron is based on their type of tube. The magnetron is a cross-field device. These are generally referred to as M-type tubes. Reflex klystron…
TEE Junction | E-Plane Tee, H-plane Tee, Magic Tee
Microwave TEE Junction Microwave Waveguide Tee junction is used for the purpose of connecting a branch or a section of a waveguide in a series or parallel to the main…
Gunn Diode: RWH Theory, Domain Formation
Gunn diode is a two-terminal but a bulk device, without any junction. It is also called a diode as it has two terminals. Gunn diodes are also −veresistance device, normally…
IMPATT Diode – Working Principle and Applications
IMPATT Diode IMPATT diode is abbreviated as an impact-ionization avalanche transit-time diode. It is an active solid-state device that operates by a reverse bias adequate to cause avalanche breakdown. This…
Directional Couplers
Directional Couplers Directional couplers are flanged, built-in waveguide assemblies which can sample a small amount of microwave power for measurement purposes. They can be designed to measure incident and/or reflected…
Magnetron Oscillator
Magnetron Oscillator Magnetron Oscillator is another type of microwave generator. In the magnetron oscillator, the magnetic field is perpendicular to the electric field and is therefore called cross-field or M-type.…
Travelling Wave Tube Amplifier
Travelling Wave Tube Amplifier Travelling wave tube amplifier is basically an amplifier, which makes use of a distributed interaction between travelling wave and electron beam. It is necessary for interaction…
