Types of Magnetron: The Various Types of Magnetron are 20-kW Conventional Metal Ceramic Magnetron 5-MW Long Anode Coaxial Magnetron Frequency agile or Dither tuned Magnetron Voltage Tunable Magnetron The Magnetron,…
Reflex Klystron Oscillator: It is possible to produce oscillations in a klystron device which has only one cavity, through which electrons pass twice. This is the Reflex Klystron Oscillator, which…
Multicavity Klystron: The design of the multicavity klystron, together with all the remaining tubes described here, relies on the fact that transit time will sooner or later terminate the usefulness…
Waveguide Switch Design: It is often necessary to prevent microwave power from following a particular path, or to force it to follow another path; as at lower frequencies, the component…
Radio Receivers Articles: Tuned Radio Frequency Receiver: The Tuned Radio Frequency Receiver is a simple “logical” receiver. A person with just a little knowledge of communications would probably expect all…
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…
Phase Discriminator: This Phase Discriminator is also known as the center-tuned discriminator or the Foster-Seeley discriminator, after its inventors. It is possible to obtain the same S-shaped response curve from…
FM Receiver Block Diagram: The FM receiver is a superheterodyne receiver, and the FM Receiver Block Diagram of Figure 6-28 shows just how similar it is to an AM receiver.…
