What is Gunn Diode? Tutorial for beginners

Gunn Diode

Gunn diode is a type of microwave diode designed for use in high-frequency devices. Due to its properties it’s often used in electronical oscillators whose frequencies can reach terahertzs. Another popular usages of Gunn diode are amplifiers, detectors etc.

Gunn diodes must be produced in special, protected environment to prevent any destructive factors from damaging it. Although it is called a diode, it is not really a diode because of it’s internal structure. It’s working principle is based on the Gunn effect named after J.B. Gunn, who discovered it.
