MIL-PRF-1/299G
NOTES:
1. This specification sheet uses accept on zero defect sampling plan in accordance with MIL-PRF-1, table III.
2. The input standing-wave ratio shall be measured at intervals of 30 MHz from F1 - 30 MHz to F4 + 30 MHz. At no
frequency in this interval shall the voltage standing wave ratio be greater than the amount specified.
3. This test shall be performed using the flanges specified in Drawing 268-JAN.
4. This test shall be performed using the mount specified in Drawing 153-JAN (or equivalent).
5. With a load standing wave ratio of less than 1.05 the voltage standing ratio produced by the tube shall be less than the
amount specified.
6. The ignitor power supply shall have an open circuit voltage of 600 V dc negative with respect to the tube body.
The ignitor series resistance shall be 1.60 Meg. The ignitor shall fire within the specified time after application of voltage.
7. Anvil in accordance with Drawing 188-JAN. An equivalent test employing MIL-STD-202, method 213 may be used provided
G level and pulse duration of shock pulse level are equivalent to that obtained using MIL-STD-1311, method 1036 with hammer
angle of 25
8. The recovery time shall be measured after 30 minutes of operation under the conditions specified.
9. To obtain copies of the JAN drawings e- mail TubeAmps@dla.mil group except for Drawing JAN-153.
