AR 10037990, Operating And Service Manual, Page: 24 / 54

POWER (fundamental), CW @ OUTPUT FLANGE:
Nominal 300 watts
Minimum 250 watts
FLATNESS: ±6 dB maximum at rated power
FREQUENCY RESPONSE: 6-18 GHz instantaneously
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
GAIN (at maximum setting): 54 dB minimum
GAIN ADJUSTMENT (continuous range): 35 dB mini-
mum
INPUT IMPEDANCE: 50 ohms, VSWR 2.5:1 maximum
OUTPUT IMPEDANCE: 50 ohms, VSWR 2.5:1 typical
MISMATCH TOLERANCE: Output power fold back
protection at reflected power exceeding 50 watts. Will
operate without damage or oscillation with any magni-
tude and phase of source and load impedance. May
oscillate with unshielded open due to coupling to in-
put. Should not be tested with connector off.
MODULATION CAPABILITY: Will faithfully reproduce
AM, FM, or pulse modulation appearing on the input
signal. AM peak envelope power limited to specified
power.
VIDEO PULSE CAPABILITY:

Pulse Rate (PRF) 100kHz max
RF Rise and Fall 30 ns max (10% to 90%)
Delay 300 ns max from pulse input to
RF 90%
Pulse width distortion ±30 ns max (50% points of
output pulse width compared to
50% points of input pulse
width)
NOISE POWER DENSITY:
(pulse on) Minus 65 dBm/Hz (maximum), Minus 70
dBm/Hz (typical)
(pulse off) Minus 140 dBm/Hz (typical)
HARMONIC DISTORTION:
Minus 5 dBc max., minus 8 dBc typ.
PRIMARY POWER: 190-260 VAC, 50/60 Hz single
phase, 2.0 KVA maximum
