Basic Radar System Block Diagram: Basic Radar System Block Diagram consists of a transmitter and a receiver, each connected to a directional antenna. The transmitter is capable of sending out…
Submarine Cables: Submarine cables use principles very much like those of coaxial cables. Thus they are coaxial, have repeaters and equalizers and have dc power fed to them, with opposite…
Applications of Tropospheric Scatter Links: Applications of Tropospheric Scatter Links also known as troposcatter is rather similar to a microwave link terminal, and indeed a typical block diagram is sufficiently like Figure…
Microwave Link in Electronic Communication: A Microwave Link in Electronic Communication performs the same functions as a copper or optic fiber cable, but in a different manner, by using point-to-point…
Telemetry in Electronic Communications: Telemetry in Electronic Communications consists of performing measurements on distant objects. Although hydraulic or wire circuits may be used for this purpose, this section will deal…
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 semiconÂductor materials.…
Tunnel Diode Equivalent Circuit: The Tunnel Diode Equivalent Circuit, when biased in the negative-resistance region, is shown in Figure 12-18. At all except the highest frequencies, the series resistance and…
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…
