Semiconductor Microwave Devices Articles: Trapatt Diode Construction and Working: The Trapatt Diode Construction and Working is derived from and closely related to the IMPATT diode. Indeed, as pointed out near…
Pulsed Ruby Laser: The Pulsed Ruby Laser is similar to the ruby cavity maser, to some extent, in that stimulation is applied to raise the chromium atoms to a higher…
Ruby Maser: As was know ferrites of certain materials have atomic systems that can be made to resonate magnetically at frequencies dependent on the atomic structure of the material and…
Gunn Diode Working Principle: A practical Gunn Diode Working Principle consists of a slice like the one shown in Figure 12-24, sometimes with a buffer layer between the active layer…
Gunn Effect: In 1963, Gunn discovered the transferred electron effect which now bears his name. This Gunn Effect is instrumental in the generation of microwave oscillations in bulk semiconductor materials.…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
