The Model 70T40G45 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where wide instantaneous bandwidth, high gain and moderate power output are required. A reliable TWT subsystem provides a conservative 70 watts minimum at the amplifier output connector. Stated power specifications are at the fundamental frequency. -
POWER (fundamental), CW, @ OUTPUT CONNECTOR -
FLATNESS: ± 5 dB maximum -
FREQUENCY RESPONSE: 40 - 45 GHz instantaneously -
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum -
GAIN (at maximum setting): 48 dB minimum -
GAIN ADJUSTMENT (continuous range): 35 dB minimum -
INPUT IMPEDANCE: 50 ohms, VSWR 2.0:1 typical -
OUTPUT IMPEDANCE: 50 ohms, VSWR 2.5:1 typical -
MISMATCH TOLERANCE: Output isolator used to offer excellent mismatch tolerance up to reflected power of 70 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 20 dBc typical -
PRIMARY POWER -
190-260 VAC -
50/60 Hz single phase -
1.0 kVA maximum -
CONNECTORS -
RF input: Type 2.4 mm female on rear panel -
RF output: Type WR-22 waveguide flange on rear panel -
RF output sample ports: Type 2.4 mm female on rear panel -
GPIB: IEEE-488 on rear panel -
Interlock: DB-15 female on rear panel -
COOLING: Forced air (self contained fans), air entry and exit in rear -
WEIGHT (approximate): 41 kg, 120 lbs -
SIZE (W x H x D): 50.3 x 25.4 x 68.6 cm, 19.8 x 10 x 27 in.
