An RC (current spiking network) is used on the driver circuit output to provide a large transient current spike to rapidly remove stored charge from the PIN diode. Typical component values are : R = 5 to 22Ω and C = 47 to 1, pf. 2) PIN diode minimum reverse DC voltage (V HIGH) is used to maintain high resistance in the OFF PIN diode state and is determined by RF frequency, incident power, duty cycle, characteristic impedance and VSWR as well by the characteristics of the PIN diode.
