CONNECTOR:
Nominal: 350 watts
Minimum:
300 watts
Linear @ 1 dB Compression : 75 watts minimum
FLATNESS: ±12 dB maximum, equalized for ±5 dB
maximum at rated power
FREQUENCY RESPONSE: 2.5-7.5 GHz instantaneously
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
GAIN (at maximum setting): 55 dB minimum
GAIN ADJUSTMENT (continuous range): 35 dB mini-
mum
INPUT IMPEDANCE: 50 ohms, VSWR 2.0:1 maximum
OUTPUT IMPEDANCE: 50 ohms, VSWR 2.5:1 typical
MISMATCH TOLERANCE: Output power foldback
protection at reflected power exceeding 60 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.

AM, FM, or pulse modulation appearing on the input
signal. AM peak envelope power limited to specified
power.

Pulse Width Distortion: ± 30 ns (50% points of out-
put pulse width compared to 50% point of input
pulse width)
NOISE POWER DENSITY:
(pulse on): Minus 75 dBm/Hz (maximum); Minus 80
dBm/Hz (typical)
(pulse off): Minus 140 dBm/Hz (typical)
HARMONIC DISTORTION: Minus 3.0 dBc maximum,
Minus 4.5 dBc typical
PRIMARY POWER: 190-260 VAC, 50/60 Hz single
phase, 3.0 KVA maximum
