If the length of the intrinsic region in IMPATT diode is 2 µm and the carrier drift velocity are 107 cm/s, then the nominal frequency of the diode is:

Question

Quizplus · Accepted Answer

The nominal frequency (f) of an IMPATT diode can be calculated using the formula f = v / (2 * L), where v is the carrier drift velocity and L is the length of the intrinsic region. Given v = 10^7 cm/s (or 10^8 m/s) and L = 2 µm (or 2 * 10^-6 m), f = 10^8 / (2 * 2 * 10^-6) = 25 GHz.
