Operation of two cavity klystron amplifier?
The power gain of a two cavity klystron amplifier is about 30 dB. In order to achieve higher overall gain, one way is to connect several two-cavity tubes in cascade, feeding the output to each of the tubes to the input of the following one. Besides using the multistage techniques, the tube manufacturers have designed and produced multi cavity klystron to sere the high-gain requirement. In a multi cavity klystron each of the intermediate cavities, placed at a distance of the bunching parameter X of 1.841 away from the previous cavity, acts as a buncher with the passing electron beam inducing a more enhanced RF voltage than the previous cavity, which in turn sets up an increased velocity modulation.
What is the advantage of a reflex klystron over a two-cavity klystron?
What is probably the primary advantage of the reflex klystron over the two-cavity klystron is the mechanism used to tune the device. The two-cavity klystron has mechanical tuning, but the reflex klystron is tuned electrically. And it doesn't take an electrical engineering degree for an investigator to figure out that electrical controls can be manipulated a whole bunch faster than a mechanical device.
What is difference between electrical angle and mechanical angle?
Electrical angle is half of mechanical angle in unipolar electrical machines. In multipolar electrical machines, the relationship between the mechanical angle and electrical angle is Electrical angle = (P/2) x Mechanical angle where: P = Number of poles.
What is a cavity combiner in a communication system?
A Cavity Combiner is a device which allows the outputs of two or more transmitters on different frequencies to be combined. It uses bandpass filters on each input to prevent the signals from the other transmitters from entering the output of a transmitter.
What are the function and purpose of rake angles?
Rake angle is usually used for cutting and machining processes. This can vary according to the materials being cut and set-up. The two types of rake angle are the back and side rake angle.
What is the difference between the two cavity klystron amplifier and reflex klystron?
klystron can act as both an amplifier and oscillator whereas a reflex klystron can act as only an oscillator. klystron needs a buncher cavity(sometimes multiple bunchers) and a catcher cavity whereas a reflex klystron needs only one cavity. klystron bunches electrons in forward direction, whereas the other bunches in the reverse direction using a reflector plate. klystron needs i/p signal (accelerating or deccelerating potential) whereas the other dont.
Name two subdivisions of the dorsal cavity in humans?
The two subdivisions of the Dorsal Cavity are the Cranial Cavity and the Vertebral Cavity.
What is the name of the two largest body cavity?
The abdominal cavity and the chest cavity are the two largest body cavities in humans.
What are the two subdivisions of the dorsal body cavity?
thoracic and abdominopelvic cavity
What are the two cavities that are separated by the roof of the mouth?
The two cavities separated by the roof of the mouth are the nasal cavity above and the oral cavity below. The nasal cavity is responsible for breathing and olfaction, while the oral cavity is used for mastication, swallowing, and speech.
What are the two major cavities of the body are called?
The two major cavities of the body are the thoracic cavity and the abdominal cavity. The thoracic cavity houses the heart and lungs, while the abdominal cavity contains organs such as the liver, stomach, and intestines.
What is the intersection beeween Two planes?
Transit.
Can a angle make two rays?
Two intersecting rays form an angle. Without two rays you do not have an angle.
What two cavities protect the central nervous system?
Dorsal cavity Cranial cavity
What are the two main cavities in the body?
The Thoracic cavity (above the diaphragm) & the Abdominal cavity (below).
What is true about the statement if two angle's are right angle's then the two angle's have an equal measure and its converse If two angle's have an equal measure then they are right angle's?
what statement about the two angles in a right tringle that do not measure 90 is true
The dorsal body cavity is subdivided into which of the following subdivisions?
The dorsal cavity is divided into the cranial cavity and the spinal cavity. These two subdivisions are continuous with each other.
