POWER OUTPUT @ 1dB COMPRESSION
Nominal ................................................................122
watts
Minimum ...............................................................100 watts
FLATNESS.....................................................................±1.5 dB typical
±2.0 dB maximum
±1.0 dB Internal Leveling
FREQUENCY RESPONSE ...............................................0.8 – 3.0 GHz, instantaneously
GAIN (at maximum setting) ...........................................51 dB minimum
GAIN ADJUSTMENT......................................................(Continuous Range)
15
dB minimum
(4096 steps remote)
INPUT IMPEDANCE.......................................................50 ohms, VSWR 2.0:1 maximum
RF POWER DISPLAY ......................................................0–150 Watts
OUTPUT IMPEDANCE ...................................................50 ohms, nominal, VSWR 2.5:1 maximum
MISMATCH TOLERANCE...............................................100% of rated power without foldback. Will operate without damage or
oscillation with any magnitude and phase of source and load impedance. (See
Application Note #27)
MODULATION CAPABILITY...........................................Will faithfully reproduce AM, FM, or pulse Modulation appearing on the input
signal.
THIRD ORDER INTERCEPT .............................................See chart. The third order intercept points for this chart have been determined
using two tones spaced 1 MHz apart. This is typical for W-CDMA systems. Closer
tone spacing such as 60 kHz generally provides about a 1db to 3db
improvement in the IP.
HARMONIC DISTORTION.............................................Minus 20 dbc, max at 100 watts
SPURIOUS ....................................................................Minus 73 dbc Typ.
PHASE LINEARITY..........................................................± 1.0 deg/100 MHz, Typ
PRIMARY POWER ..........................................................(Selected Automatically)
90-132, 180-264 VAC
50/60 Hz, single phase
1200 watts maximum
CONNECTORS
