MIL-PRF-19500/611A

NOTES:

1. The input waveform is supplied by a pulsed generator with the following characteristics: tr ≤ 15 ns, tf ≤ 15 ns, ZOUT = 50 Ω, PW =

10 �s, duty cycle ≤ 2%.

2. Output waveforms are monitored on an oscilloscope with the following characteristics: tr ≤ 1.0 ns, ZIN ≥ 10 MΩ, CIN ≤ 11.5 pF.

3. Resistors shall be noninductive types.

4. The dc power supplies may require additional bypassing in order to minimize ringing.

5. The input pulse voltages and supply voltages (-4 V dc and +100 V dc) are nominal and shall be adjusted to obtain IB1 = -IB2 = 30

mA and IC = 1 A with .02 �f capacitor removed.
