FUNCTIONAL DESCRIPTION
IF. Frequency: 59.5 1.5 mc
Bandwidth: 6 db, 8 to 11 mc
Radar Identification Sets AN/UPX-5, -5A, and -5B
Duty Cycle: 0.1% while carrying rf pulses of
respond to interrogations from radar recognition sets for
10-kw peak power
the purpose of self-identification. They receive paired-
Minimum Output: 300 watts at 500 pps
pulse interrogation signals and transmit single-pulse
Pulse Width: 0.9 to 1.3 sec at 50% peak am-
