MIL-PRF-39012/5H
Voltage standing wave ratio (VSWR): From 500 to 11 GHz, or approximately 80 percent of upper
cutoff frequency of the cable, whichever is lower.
From 500 MHz to 9 GHz: 1.35 maximum.
From 9 to 11 GHz: 1.50 maximum.
Swept frequency VSWR test setup:
Item 6: VSWR shall be less than 1.008 + .002 F (F in GHz).
Item 16: VSWR shall be less than 1.008 + .002 F (F in GHz).
Second step of VSWR checkout procedure VSWR shall be less than 1.012 + .004 F (F in GHz).
Group B inspection VSWR shall be less than 1.024 +.007 F (F in GHz).
Qualification and group C inspection VSWR shall not exceed 1.08.
Connector durability: 500 cycles minimum at 12 cycles/minute maximum. The connector shall meet
the mating characteristics and force to engage and disengage requirements.
Contact resistance: In milliohms maximum.
