Cut-off Frequency in Microwave Semiconductor Devices Formulas
Cut-off Frequency is defined as corner frequency is a boundary in system’s frequency response at which energy flowing through system begins to be reduced rather than passing through. And is denoted by f
co
. Cut-off Frequency is usually measured using the Hertz for Frequency. Note that the value of Cut-off Frequency is always positive.

FAQ
What is the Cut-off Frequency?
Cut-off Frequency is defined as corner frequency is a boundary in system’s frequency response at which energy flowing through system begins to be reduced rather than passing through. Cut-off Frequency is usually measured using the Hertz for Frequency. Note that the value of Cut-off Frequency is always positive.
Can the Cut-off Frequency be negative?
No, the Cut-off Frequency, measured in Frequency cannot be negative.
What unit is used to measure Cut-off Frequency?
Cut-off Frequency is usually measured using the Hertz[Hz] for Frequency. Petahertz[Hz], Terahertz[Hz], Gigahertz[Hz] are the few other units in which Cut-off Frequency can be measured.
