SPECIFICATIONS
The Model 35ST1G18 is a self contained, forced air cooled, broadband hybrid solid state and traveling wave tube (TWT) microwave amplifier designed for applications where low harmonic content is required in sub-band ranges and where high gain and moderate power output are required. A reliable amplifier system provides a conservative 35 watts minimum at the amplifier output connector with low harmonics. Stated power specifications are at the fundamental frequency. POWER (fundamental), CW, @ OUTPUT CONNECTOR Nominal:   50 watts Minimum:   45 watts from 0.8 to 4.2 GHz 35 watts from 4.2 to 18 GHz Linear @ 1dB Compression:   10 watts minimum FLATNESS ±3 dB maximum, 0.8 – 4.2 GHz ±10 dB maximum, 4.2 – 18 GHz FREQUENCY RESPONSE:    0.8 - 18 GHz in one of four selectable sub-bands INPUT FOR RATED OUTPUT:   1.0 milliwatt maximum GAIN (at maximum setting):   45 dB minimum GAIN ADJUSTMENT (continuous range) 10 dB minimum (0.8 – 4.2 GHz) 35 dB minimum (4.2 – 18 GHz) INPUT IMPEDANCE:   50 ohms, VSWR 2.5:1 maximum OUTPUT IMPEDANCE:   50 ohms, VSWR 2.5:1 typical MISMATCH TOLERANCE:   100% of rated power without foldback from 0.8 – 4.2 GHz. Output power foldback protection above 4.2 GHz at reflected power exceeding 20 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. NOISE POWER DENSITY (from 4.2 – 18 GHz) Minus 80 dBm/Hz (maximum) Minus 90 dBm/Hz (typical) HARMONIC DISTORTION (in user selectable sub-band (at 35 watts) Minus 20dBc maximum, Minus 30dBc typical PRIMARY POWER 99-260 VAC 50/60 Hz single phase 1400 VA maximum CONNECTORS RF input:   Type N precision female on rear panel RF output:   Type N precision female on rear panel RF output sample port:   Type N precision female on rear panel GPIB:   IEEE-488 female Interlock:   DB-15 female on rear panel COOLING:   Forced air (self contained fans), air entry and exit in rear. SIZE (W x H x D):   19.8 x 19 x 29 in., 50.3 x 48 x 74 cm. WEIGHT (approximate):   185 lbs, 84 kg
