Types of Magnetron

Types of Magnetron: The Types of Magnetron, perhaps more than any other microwave tube, lends itself to a variety of types, designs and arrangements. Magnetrons using hole-­and-slot, vane and rising-sun cavities have already been discussed. Figure 11-16a shows the construction of another Vane-type magnetron, this time using an all-metal-ceramic structure. This type is in current […]

Cavity Magnetron Working

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 structure with permanent cavities. As shown in Figure 11-10, the cylindrical cathode is surrounded by the anode with cavities, and […]

Reflex Klystron Oscillator

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 Reflex Klystron Oscillator is a low-power, low-efficiency microwave oscillator, illustrated schematically in Figure 11-8. It has an electron gun similar […]
