SPECIFICATIONS

The Model 20ST1G18A is a self contained, forced air cooled, broadband hybrid solid state and traveling wave tube (TWT) microwave amplifier designed for applications where wide instantaneous bandwidth, high gain and moderate power output are required.

POWER (fundamental), CW, @ OUTPUT CONNECTOR
- Nominal: 30 watts
- Minimum: 20 watts
- Linear @ 1dB Compression: 10 watts minimum
FLATNESS
- ±3 dB maximum 0.8 – 4.2 GHz
- ±9 dB maximum, 4.2 - 18 GHz
FREQUENCY RESPONSE
- 0.8 - 18 GHz in one of two selectable sub-bands
- 0.8 – 4.2 GHz and 4.2 - 18 GHz
INPUT FOR RATED OUTPUT: 1.0 milliwatt maximum
GAIN (at maximum setting): 43 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 2.0:1 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 (at 20 watts)

0.8–4.2 GHz, Minus 20 dBc maximum, Minus 30 dBc typical
4.2-4.5 GHz; Minus 0 dBc maximum, Minus 1 dBc typical
4.5-5 GHz; Minus 1 dBc maximum, Minus 2 dBc typical
5-7 GHz; Minus 2.5 dBc maximum, Minus 4 dBc typical
7-10 GHz; Minus 5 dBc maximum, Minus 9 dBc typical
10-12 GHz; Minus 8 dBc maximum, Minus 12 dBc typical
Above 12 GHz; Minus 20 dBc maximum, Minus 30 dBc typical
