Gunn Diodes

Peculiar Parts, the series

I’ve talked about different types of diodes in previous Peculiar Parts instalments because there just seems to be so many unique types made in the early days of semiconductor devices. This time I wanted to look at Gunn diodes which are common in RF circuits but can barely be classified as a diode at all.

What is a Gunn Diode?
Gunn diode is two terminals electronic device, which is composed of only one type of doped semiconductor i.e N-region. The unique property of Gunn diode is that it works in Negative differential resistance region, which means it can be used to generate microwaves frequencies of 0 to 100 GHz. The Gunn Diode is also known as Transferred Electronic Device (TED) because it is composed of N-region, and N-region semiconductor has electrons as a majority carrier, and the Transferred Electronic Devices (TEDs) uses such materials which have electrons in the majority.
