The Model 200TR4G8 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.
-
POWER (fundamental), CW @ OUTPUT FLANGE
-
Nominal: 262 watts
-
Minimum: 200 watts
-
FLATNESS: ±12 dB maximum
-
FREQUENCY RESPONSE: 4-8 GHz instantaneously
-
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
-
GAIN (at maximum setting): 53 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 fold back protection at reflected power exceeding 40 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.
