The Model 5700TP12G18 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier system designed for pulse applications at low to moderate duty factors where instantaneous bandwidth and high gain are required. Reliable TWT subsystems provide a conservative 5700 watts minimum peak RF pulse power at the amplifier output connector. Stated power specifications are at the fundamental frequency. -
POWER (Fundamental), Peak Pulse, @ Output -
Nominal: 7,000 watts -
Minimum: 5,700 watts -
FLATNESS: ±10 dB maximum, ±5 dB at rated power -
FREQUENCY RESPONSE: 12-18 GHz -
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum -
GAIN (at maximum setting): 67 dB minimum -
GAIN ADJUSTMENT (continuous range): 35 dB minimum -
INPUT IMPEDANCE: 50 ohms, VSWR 2.5:1 maximum -
OUTPUT IMPEDANCE: 50 ohms, VSWR 2.5:1 typical -
MISMATCH TOLERANCE: Output pulse width foldback protection at peak reflected power exceeding 3000 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. -
