This is a simple diode that exhibits non-linear impedance. These diodes are mostly used at microwave detection and mixing.ConstructionA semi-conductor pellet is mounted on a metal base. A spring-loaded wire is connected with a sharp point to this silicon pellet. This can be easily mounted into coaxial or waveguide lines. The below figure gives a clear picture of this.OperationWith the contact between semiconductor and the metal, a depletion region is formed. The metal region has a smaller depletion width, comparatively. When contact is made, electron flow occurs from semi-conductor to the metal. This depletion builds up a positive space charge ...

Generally, if the frequency of a signal or a particular band of signals is high, the bandwidth utilization is high as the signal provides more space for the other signals to get accumulated. But the high-frequency signals can’t travel long distances without getting attenuated. We have studied the transmission lines that help the signals to travel longer distances.A WaveguideMicrowaves propagate through microwave circuits, components and devices, which act as a part of Microwave transmission lines, broadly called as Waveguides.DefinitionA hollow metallic tube of the uniform cross section for transmitting electromagnetic waves by successive reflections from the inner walls of the ...
