*PW=30μs, Duty Cycle ≤ 2.0%.
1) All gate breakdown voltages are measured while the device is conducting rated gate current. This insures that the gate voltage limiting network is functioning properly.
2) This parameter must be measured with bias voltages applied for less than five (5) seconds to avoid overheating.
3) Gps is defined as the change in Gps from the value at VGG=7.0V.
4) Amplitude at input from local oscillator is 3 volts RMS.
