FAQ

What is Cut-off frequency of varactor diode?
The Cut-off frequency of varactor diode is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced rather than passing through and is represented as F=1/(2*pi*Rse*CT) or Cut-off frequency=1/(2*pi*Series field resistance*Capacitance of varactor Diode). Series field resistance is resistance just like the filed resistance but it is connected to a series field and The capacitance of Varactor Diode is the ability of a component or circuit to collect and store energy in the form of an electrical charge.
