The PIN diode obeys the common diode equation for very low-frequency signals. At greater frequencies, the diode looks like an almost best (pretty linear, even for big signals) resistor. The P-I-N diode has a relatively massive saved charge adrift in a very thick intrinsic area. In a very low-enough frequency, https://coaxial-switch98357.blog5.net/82652870/coaxial-switch-an-overview
