The Model 1000T8G18B 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. Reliable TWT subsystems provide a conservative 1000 watts minimum at the amplifier output connector over most of the frequency range. Stated power specifications are at fundamental frequency. -
POWER (fundamental) , CW, @ OUTPUT CONNECTOR -
FLATNESS -
FREQUENCY RESPONSE: 7.5 - 18 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. -
