MIL-PRF-39012/3H
Voltage standing wave ratio (VSWR): From 500 MHz to 11 GHz, or approximately 80 percent of upper
cutoff frequency of the cable, whichever is lower; 1.30 maximum (1.45 max. to 11 GHz for X503 and
-X504).
Swept frequency VSWR test setup
Item 6: VSWR shall be less than 1.008 +.002 F (F in GHz).
