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).
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.
0.25 dB/day at constant drive and temperature.
10 dB peak-to-peak (typical), except M-Band 15 dB (typical)
50 Ohms nominal
2.0:1 typical
2.0:1 typical
1.3:1 max. for full spec compliance, 2.0:1 max. for no damage.
Any value without damage if Option D is included.
-50 dBc typical excluding harmonics and residual modulation
-40 dBc
Less than 4 kHz peak-to-peak in any 5 MHz band
2.5/dB typical at 6 dB below rated output
35 dB max.
-3 dBc at lower band edge decreasing to -15 dBc (typical) at upper band edge without optional
harmonic filter.
