A2I20D040N Switching Time

Hello everyone!

I understand from the datasheet of A2I20D040N that by setting the gate voltages one could turn the amplifier off or on. But it doesn't mention the switching speed of the amplifier. 

I am planning to use this for a TDMA system and switching speed is a critical spec. What are the rise and fall times of the amplifier while switching between on and off?

Thank you!

I got the following measured data:

Conditions:

Set capacitance at the gate to minimum to have a faster switching time (in this case only a 1 nF capacitor was used).

Use a series resistor after the gate power supply to dampen down any sorts of potential overshoot (in this case 50 Ohm is used).

Results:
Input signal to the second stage gate rise time 675ns. RF output rise time 693ns.
