SPECIFICATIONS

The Model 40T4G18 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where low harmonic content is required in sub-band ranges and where wide instantaneous bandwidth, high gain and moderate power output are required. A reliable TWT provides a conservative 40 watts minimum at the amplifier output connector, 30 watts in low harmonic modes. Stated power specifications are at the fundamental frequency.

POWER (fundamental), CW, @ OUTPUT CONNECTOR

Nominal: 50 watts
Minimum: 40 watts, 30 watts in low harmonic mode
Linear @ 1dB Compression: 10 watts minimum

FLATNESS: ±10 dB maximum, 4.2 - 18 GHz
FREQUENCY RESPONSE: 4.2-18 GHz instantaneously or one of three selectable sub-bands in low harmonic mode
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
GAIN (at maximum setting): 46 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 20 watts (13 watts in low harmonic mode). 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

Minus 80 dBm/Hz (maximum)
Minus 90 dBm/Hz (typical)

HARMONIC DISTORTION (in user selectable sub-band at 30 watts)

HARMONIC DISTORTION (full band at 40 watts)

4.2-4.5 GHz; Plus 2.5 dBc maximum, Minus 0 dBc typical
4.5-6 GHz; Plus 0.5 dBc maximum, Minus 1 dBc typical
6-8 GHz; Minus 4 dBc maximum, Minus 6 dBc typical
8-10 GHz; Minus 6 dBc maximum, Minus 9 dBc typical
Above 10 GHz; Minus 10 dBc maximum, Minus 15 dBc typical
