Variables Used
Source Resistance - (Measured in Ohm) - Source Resistance a purely resistive device can be experimentally determined by increasingly loading the device.
Drain Resistance - (Measured in Ohm) - Drain resistance is the ratio of change in drain to source voltage to corresponding change in drain current for a constant gate to source voltage.
Cut-off Frequency MESFET - (Measured in Hertz) - Cut-off frequency MESFET 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.
Maximum Frequency of Oscillations - (Measured in Hertz) - Maximum frequency of oscillations is defined as the practical upper bound for useful circuit operation with MESFET.
Gate Metallization Resistance - (Measured in Ohm) - Gate metallization resistance is defined as the resistance of metallization of a FET gate stripe that has effect of placing a non-linear resistance in series with the gate junction.
Input Resistance - (Measured in Ohm) - Input resistance MESFET is defined as the total internal resistance as experienced by MESFET.
