Gunn diode

The Gunn diode has similar high frequency capability and can handle more power.

This means a Gunn diode has a region of negative differential resistance.

This led to the invention of the Gunn diode, a miniature microwave generator.

Because of their high frequency capability, Gunn diodes are mainly used at microwave frequencies and above.

It is used in the manufacture of Gunn diodes for generation of microwaves.

A Gunn diode oscillator and waveguide are used as a motion detector for automatic door openers.

Klystrons can produce far higher microwave power outputs than solid state microwave devices such as Gunn diodes.

The laboratory methods that are used to select materials for the manufacture of Gunn diodes include angle-resolved photoemission spectroscopy.

The Gunn diode is mounted in a cavity tuned to resonate at twice the fundamental frequency of the diode.

Gunn diodes are used to build oscillators in the 10 GHz to high (THz) frequency range.

Tunnel diodes and Gunn diodes exhibit a negative resistance region in their IV (current - voltage) curve.

Many electronic oscillator circuits use one-port negative resistance devices, such as magnetron tubes, tunnel diodes and Gunn diodes.

By virtue of their low voltage operation, Gunn diodes can serve as microwave frequency generators for very low powered (few-milliwatt) microwave transmitters.

A Gunn diode, also known as a transferred electron device (TED), is a form of diode, a semiconductor electronic component, used in high-frequency electronics.

In the Gunn diode, three regions exist: two of them are heavily N-doped on each terminal, with a thin layer of lightly doped material in between.

A reflection amplifier is a type of microwave amplifier circuit utilizing negative resistance diodes such as tunnel diodes and Gunn diodes.

He discovered the Gunn Effect, which led to the invention of the Gunn diode, the first inexpensive source of microwave power that did not require vacuum tubes.

It is the theory behind the operation of the Gunn diode as well as several other microwave semiconductor devices, which are used practically in electronic oscillators to produce microwave power.

Later, at the IBM Research Laboratories in the U.S., he discovered the Gunn effect used in the Gunn diode.

These include tunnel diodes, Gunn diodes, IMPATT diodes, magnetron tubes, and unijunction transistors.

It is usually implemented with a resistor or current source, a capacitor, and a "threshold" device such as a neon lamp, thyratron, diac, unijunction transistor, or Gunn diode.

Low-power microwave sources use solid-state devices such as the field-effect transistor (at least at lower frequencies), tunnel diodes, Gunn diodes, and IMPATT diodes.

Ridley-Watkins-Hilsum theory that provided the theoretical basis of the Gunn diode, and his research helped form the basis of modern LCD technology, bringing in over £100m to the UK government.

This results in an overall decrease of current for higher voltage until all electrons are in the "slow" band and this is the principle behind operation of a Gunn diode, which can display negative differential resistivity.
