Specifications
Frequency Range
Rated Output Power
4.0 to 18 GHz (see Selection Guide)
20 Watts CW. Saturated output power may exceed rated power by 6 dB or more near band center.
Output power is reduced by the insertion loss of all microwave options added at the output. (Options C,
D, E, J).
Small Signal Gain
35 to 40 dB (see Selection Guide). Typically 10 to 20 dB higher near band center. Gain at Saturated
Power is typically 5 dB less than small signal gain. Gain is reduced by the insertion loss of all
microwave options.
Gain Stability
Gain Variation
Impedance
0.25 dB/day at constant drive and temperature.

Noise & Spurious
Residual AM
-50 dBc typical excluding harmonics and residual modulation
-40 dBc
Residual FM
