Surface Acoustic Waves Devices(SAW): Surface Acoustic Waves Devices may be propagated on the surfaces of solid piezoelectric materials, at frequencies in the VHF and UHF regions. Devices employing SAW principles were first discussed in the…
Stripline and Microstrip Transmission Line: Stripline and Microstrip Transmission Line are physically related to transmission lines but are covered here because they are microwave circuits used in conjunction with semiconductor microwave devices. As illustrated of…
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 the beginning of this section, at first it was…
Crossed Field Amplifier: The Crossed Field Amplifier is a microwave power amplifier based on the magnetron and looking very much like it. It is a cross between the TWT and the magnetron in its operation.…
Types of Travelling Wave Tubes: The TWT is the most versatile and most frequently used microwave tube. Four Types of Travelling Wave Tubes, each with particular applications and performance requirements. These are now described. TWT…
Traveling Wave Tube Working(TWT): Like the multicavity klystron, the Traveling Wave Tube Working is a linear-beam tube used as a microwave amplifier. Unlike the klystron, however, it is a device in which the interaction between…
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, perhaps more than any other…
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 magnetic field and an anode…
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 will now be described. The…
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 of any orthodox tube. They…
