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 TWT and Two Cavity Klystron
Difference Between TWT and Two Cavity Klystron Two Cavity Klystron A two-cavity klystron amplifier is shown in the figure. Two cavity klystron is basically a velocity modulated tube. Here input…
Waveguide and its types
A waveguide is just a hollow metallic tube that may be rectangular or circular in shape and is used to guide the microwaves. Waveguides are constructed of brass, copper, or…
Reflex Klystron Amplifier
Klystron Amplifier To remove the limitation of traditional tubes, microwave tubes are constructed. Microwave tubes take a large transit time for the required operation. The basic principle of operation of…
