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…
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…
Cryogenically Cooled Amplifiers: The term solid-state is used deliberately here; it does not mean "semiconductor." In terms of the somewhat older maser parlance, it means the opposite of gaseous, i.e.,…
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…
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…
Resonators and Waveguides Articles: Rectangular Waveguides: As we know already that the term skin effect indicated that the majority of the current flow (at very high frequencies) will occur mostly…
