with high multiples.

The high-frequency resistance is inversely proportional to the DC bias current through the diode. A PIN diode, suitably biased, therefore acts as a variable resistor. This high-frequency resistance may vary over a wide range (from 0.1 ? to 10 k? in some cases; the useful range is smaller, though).

The wide intrinsic region also means the diode will have a low capacitance when reverse-biased.

In a PIN diode the depletion region exists almost completely within the intrinsic
