PIN diodes are occasionally created for use as input protection devices for high-frequency examination probes as well as other circuits. In case the input signal is little, the PIN diode has negligible influence, presenting only a small parasitic capacitance. Not like a rectifier diode, it doesn't existing a nonlinear resistance https://myleskdmhc.blogstival.com/56065281/not-known-factual-statements-about-pin-diode-switch
