The Model 1000T2G4 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth, high gain and high power output are required. A reliable TWT provides a conservative 1000 watts minimum at the amplifier output connector. Stated power specifications are at the fundamental frequency. -
POWER (fundamental), CW, @ OUTPUT CONNECTOR -
FLATNESS: ±4 dB maximum, ±3 dB maximum at rated power -
FREQUENCY RESPONSE: 2 - 4 GHz instantaneously -
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum -
GAIN (at maximum setting): 60 dB minimum -
GAIN ADJUSTMENT (continuous range): 35 dB minimum -
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 200 watts. Will operate without damage or oscillation with any magnitude and phase of source and load impedance. May oscillate with unshielded open due to coupling to input. 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. -
NOISE POWER DENSITY -
HARMONIC DISTORTION: Minus 6 dBc maximum, Minus 10 dBc typical -
CONNECTORS -
RF input: Type N female on rear panel -
RF output: 1-5/8” EIA on rear panel -
RF output sample ports (forward and reflected): Type N female on rear panel -
GPIB: IEEE-488 female on rear panel -
Interlock: DB-15 female on rear panel -
COOLING: Forced air (self contained fans), air entry and exit in rear. -
ENVIRONMENT: 0-50 degrees C operating, (derate 2 degrees C per 1000 feet above 3000 ft) -
HUMIDITY: To 95% RH without condensation
