Travelling Wave Tube (TWT)

A travelling wave tube is a high power amplifier used for the amplification of microwave signals up to a wide range. It is a special type of vacuum tube that offers an operating frequency ranging between 300 MHz to 50 GHz. Travelling wave tubes are non-resonant structures that offer continuous interaction of applied RF field …

Magnetron

Definition: A magnetron is a device that generates high power electromagnetic wave. It is basically considered as a self-excited microwave oscillator. And is also known as a crossed-field device. The reason behind calling it so is that the electric and magnetic field produced inside the tube are mutually perpendicular to each other thus the two …

Gunn Diode

Definition: A Gunn diode is a semiconductor device formed by only N-type material. It is also termed as a transferred electron device. As in n-type material, electrons acts as majority carriers and these are transferred from one valley to another. It is a two terminal device basically made up of semiconductor material like GaAs, InP …

Waveguides

Definition: Waveguides are a special category of transmission line that is used to guide (direct) the waves (radiation) along the length of the tube. These are typically hollow metallic tube which acts as the medium to transfer or transmit the power. In waveguides, the energy is propagated through a tube. It can be either rectangular …

Transmission Lines

Definition: Transmission lines are the conductors that serve as a path for transmitting (sending) electrical waves (energy) through them. These basically forms a connection between transmitter and receiver in order to permit signal transmission. Transmission lines in microwave engineering are known as distributed parameter networks. As their voltage and current shows variation over its entire …
