construction and working of impatt diode pdf

Abstract

In many respects, the IMPATT diode structure is very similar to that of many other forms of diode, and in particular the standard PN junction diode or the Schottky diode.However the differences in its construction and fabrication mean that it is able to operate in its avalanche mode whether the transit time provides the negative resistance.
There is a variety of structures that are used for the IMPATT diode. All are variations of a basic PN junction and usually there is an intrinsic layer, ....etc

A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, and radar transmitters, and to generate the drive power for modern particle accelerators. ....etc

SSH is a highly successful multipurpose protocol used for both
interactive shells and transport layer mechanisms. Tatu Yl nen of Helsinki University of Technology developed SSH. But most implementations of SSH reduces its
functionality as bulk data transport tool in high performance
network environments.adoption of strong, cryptographically
secure authentication methods for accessing remote systems and
resources came because of the weak security of FTP and telnet. SSH is widely available as both an open source and
commercial product for ....etc

When piezoelectric materials are under pressure, the pressure causes changes along the surface of the material, these pressure differences result in compression along one surface and strain along the other one. As a result, the positive charges collect on one side of the material, and the negative charges collect on the opposite side. This generator effect converts mechanical energy into electricity. In the reverse piezoelectric effect, used in buzzers, applying an electrical field causes the length of the surface to change and converts electri ....etc

Working and construction of electric fan

An electric fan is an electric motor to which the blats are fixed so that then the motor of the fan rotates ,the balds through the air A D.C fan are of DC series motor in which the rotating part armature is connected in series with the stationary part and when the current is given to the motor , the magnetic field is set up in the field winding which experience a force in the armature to move it at right angle to the feed and balds attached with shaft of armature displaced the air. the same principle ....etc

A jet engine is a reaction engine that discharges a jet of rapid motion that generates thrust by jet propulsion. This broad definition includes air jet engines (turbojets, turbojets, jet jets, and jet jets) and airless jet engines (such as rocket engines). In general, jet engines are combustion engines.In common parlance, the term jet engine refers to an internal combustion air jet engine. These typically feature a turbine-driven rotary air compressor, with surplus energy providing thrust via a propellant nozzle - this process is known as th ....etc
