The Model 500T1G2 is a self contained, forced air-cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth and high gain are required. A reliable TWT provides a conservative 500 watts minimum at the amplifier output connector. Stated power specifications are at fundamental frequency.
-
POWER (fundamental), CW, @ OUTPUT CONNECTOR
-
FLATNESS
-
FREQUENCY RESPONSE: 1–2.5 GHz instantaneously
-
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
-
GAIN (at maximum setting): 57 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 100 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.
