The Model 200T26z5G40 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 200 watts minimum at the amplifier output connector. Stated power specifications are at the fundamental frequency. -
POWER (fundamental), CW, @ OUTPUT CONNECTOR -
FLATNESS: ± 10 dB maximum -
FREQUENCY RESPONSE: 26.5 – 40 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 foldback 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. -
MODULATION CAPABILITY: Will faithfully reproduce AM, FM, or pulse modulation appearing on the input signal. AM peak envelope power limited to specified power. -

Pulse Width: 0.1 microseconds min -
Pulse Rate (PRF): 10 kHz max -
Duty Cycle: Some restrictions apply. Contact AR with application requirements. -
RF Rise and Fall: 100 ns max (10% to 90%) -
Delay: 500 ns max from pulse input to RF90% -
Pulse width distortion: 200 ns max (50% points of output pulse width compared to 50% points of input pulse width) -
Noise Power Density, (pulse off): Minus 140 dBm/Hz (typical) -
Pulse Off Isolation: 80 dB minimum, 90 dB typical -
Pulse Input: TTL Level, 50 Ohm nominal termination, high level enables RF when video pulsing mode is selected. -
