Specifications
Frequency Range: 1 to 18 GHz (see selection guide)
Rated Output Power: 100 or 200 Watts CW. Saturated output power generally
exceeds rated power by 1.5 to 3 db near band center.
The insertion loss of options added at the output will
reduce power delivered to the output connector.
30 to 37 dB at rated power (see selection guide).
Typical gain is 4 dB above spec at band edges and 10
dB above spec at band center. Gain is reduced by all
microwave options (see option L for higher gain.
Gain Stability:
±0.25 dB/day at constant drive and temperature.
Gain Variation:
10 dB peak-to-peak typical across all bands except 8-18
GHz where it is 15 dB typical.
Input/Output impedance:
50 Ohms nominal
VSWR:
Input: 2.0:1 typical
Output: 2.0:1 typical
Load: 1.5:1 max for full spec. Compliance;
2.0:1 max for no damage without option M. Any
value with option M
Noise & Spurious:
-50 dBc typical excluding harmonics.
Residual AM:
-40 dBc up to 10 KHz
-20 (1+ log f) dBc, 10 to 500 KHz
-80 dBc above 500 KHz
Residual FM:
Less than 4 KHz peak-to-peak for 0 to 5 MHz from
carrier.
AM/PM Conversion:
2.5-degrees/dB max at 6 dB below rated output power.
Noise figure:
40 dB max, 20 dB with option L
Harmonic Content:
-3dBc typical at lower band edge decreasing to –15 dBc
typical at upper band edge.
