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,…
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…
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…
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…
Difference Between TWT and Two Cavity Klystron
Definition of Two Cavity Klystron and TWT Amplifier Two Cavity Klystron A two-cavity klystron amplifier is shown in the figure. Two cavity klystron is basically a velocity modulated tube. Here…
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 −ve resistance device,…
