Description

The most important property of the PIN diode is the fact that it can, under certain circumstances, behave as an almost pure resistance at RF frequencies, with a resistance value that can be varied over a range of approximately 1 Ω to 10 KΩ through the use of a DC or low frequency control current. This article describes the important properties of the PIN diode and illustrates how it can be applied in a variety of RF control circuits.
