SPECIFICATIONS

The Model 250T8G18 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: 300 watts
- Minimum: 250 watts
- Linear @ 1dB Compression: 70 watts minimum
FLATNESS: ±12 dB maximum, equalized for ±5 dB maximum at rated power
FREQUENCY RESPONSE: 7.5-18 GHz instantaneously
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
GAIN (at maximum setting): 54 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 50 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.

VIDEO PULSE CAPABILITY

Pulse Width: 0.05 microseconds min
Pulse Rate (PRF): 100kHz max
RF Rise and Fall: 30 ns max (10% to 90%)
Delay: 300 ns max from pulse input to RF 90%
Pulse width distortion: ±30 ns max (50% points of output pulse width compared to 50% points of input pulse width)

NOISE POWER DENSITY

(pulse on): Minus 70 dBm/Hz (maximum), Minus 72 dBm/Hz (typical)
(pulse off): Minus 140 dBm/Hz (typical)

HARMONIC DISTORTION

Below 10 GHz, minus 5 dBc max., minus 7 dBc typ.
10-12 GHz, minus 8 dBc max., minus 12 dBc typ.
Above 12 GHz, minus 20 dBc max., minus 30 dBc typ.

PRIMARY POWER: 190-260 VAC, 50/60 Hz single phase, 2.5 KVA maximum

CONNECTORS

RF input: Type N female on rear panel
RF output: Type WRD –750D24 waveguide flange on rear panel
RF output sample port: Type N female on rear panel
GPIB: IEEE-488 (f) on rear panel
Interlock: DB-15 (f) on rear panel
Video: BNC-female on rear panel

COOLING: Forced air (self contained fans), air entry and exit in rear.
