Phased Array Radars: Phased Array Radars - Introduction With some notable exceptions, the vast majority of radars have to cover an area in searching and/or tracking, rather than always being…
Pulsed Radar System Block Diagram: A very Pulsed Radar System Block Diagram set was shown in Figure 16-1. A more detailed block diagram will now be given, and it will…
Telegraphy in Electronic Communications: Telegraphy in Electronic Communications that employs typewriter like machines operating at a maximum speed of about 60 words per minute (wpm) to send written messages from…
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…
Negative Resistance Amplifier: The classical application of the tunnel diode was in microwave oscillators, especially after it was realized that the secret of stable oscillations lay in loosely coupling the…
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…
Cavity Magnetron Working: The Cavity Magnetron Working, which will be referred to as the magnetron, is a diode, usually of cylindrical construction. It employs a radial electric field, an axial…
Ratio Detector Circuit: In the Foster-Seeley discriminator, changes in the magnitude of the input signal will give rise to amplitude changes in the resulting output voltage. This makes prior limiting…
