Gate Length of MESFET Solution

Follow our step by step solution on how to calculate Gate Length of MESFET?

FIRST Step Consider the formula

L gate = \frac{V s}{4 \cdot π \cdot f co}

Next Step Substitute values of Variables

∴

L gate = \frac{5mm/s}{4 \cdot π \cdot 30.05Hz}

Next Step Substitute values of Constants

∴

L gate = \frac{5mm/s}{4 \cdot 3.1416 \cdot 30.05Hz}

Next Step Convert Units

∴

L gate = \frac{0.005m/s}{4 \cdot 3.1416 \cdot 30.05Hz}

Next Step Prepare to Evaluate

∴

L gate = \frac{0.005}{4 \cdot 3.1416 \cdot 30.05}

Next Step Evaluate

∴

L gate = 1.32408438512392E-05m

Next Step Convert to Output's Unit

∴

L gate = 13.2408438512392μm

LAST Step Rounding Answer

∴

L gate = 13.2408μm
