Variable Attenuators  
Models 9003, 9004, 9009, 9010 & 9011 dc to 18.0 GHz  
Manual Step, Ruggedized SMA Connectors  
2 Watt  
Description  
The Model 9000 series Step Attenuators are broadband  
miniature step attenuators that provide excellent perfor-  
mance characteristics suitable for use in high reliability 50  
ohm systems and applications requiring extra-small compo-  
nents for the precision control of signal levels. The Model  
9000 series can be used either as input or output attenua-  
tors in signal sources, receivers, field strength meters,  
spectrum analyzers, etc.  
The SMA connector furnished on all models are available in  
either standard or right-angle configuration. The sex of front  
and rear connector is optional (refer to connector specifica-  
tion for specific combinations available). A knob(s), marked  
appropriately, is supplied with each unit.  
Features  
o
Broadband - Available in a choice of frequency ranges:  
dc to 4, dc to 8, dc to 12.4 and dc to 18 GHz.  
o
Wide Choice of Attenuation Ranges - A choice of five  
standard attenuation ranges is available: 0 to 9.0, 0 to  
69 and 0 to 99 dB in 1 dB steps, and 0 to 60 and 0 to  
90 dB in 10 dB steps.  
Specifications  
NOMINAL IMPEDANCE: 50 Ω  
FREQUENCY RANGE (add Model No. Prefix to  
Designate Range):  
o
o
Environmental - Designed to meet most environmen-  
tal requirements of MIL-A-24215 (Vibration, Shock,  
Relative Humidity to 95% and Altitude).  
In-line Configuration - Passivated stainless steel SMA  
connector are set parallel with control shaft (except  
units with right angle connector) to reduce volume for  
applications where space is critical. All models are bidi-  
rectional.  
All Models:  
dc to 4.0 GHz (AC)  
dc to 18.0 GHz (AF)  
Standard Incremental Attenuation Range:  
Model 9009:  
Model 9003:  
Model 9004:  
Model 9010:  
Model 9011:  
0 to 9 dB in 1 dB steps  
0 to 69 dB in 1 dB steps  
0 to 99 dB in 1 dB steps  
0 to 60 dB in 10 dB steps  
0 to 90 dB in 10 dB steps  
o
Precise Incremental Attenuation Accuracy - Model  
9000 series has flat frequency response and small  
deviation from nominal attenuation at all settings (e.g.,  
deviation is only +2.5 dB at 99 dB setting at 18 GHz).  
MAXIMUM SWR:  
o
o
o
Excellent Repeatability and Long Switch Life.  
Custom Configurations Available Upon Request.  
Highly Accurate Detent Stepping - Direct drive of  
attenuator drums eliminates gears and provides for  
excellent repeatability.

o
Safety Mechanical Stop - A mechanical stop between  
maximum and 0 attenuation positions on all models  
except 0-9 dB unit is provided to prevent large power  
changes at attenuator output from damaging sensitive  
equipment.  
POWER RATING: 2 watts average to 25°C ambient  
temperature, derated linearly to 1 watt @ 54°C. 200 watts  
peak (5 μsec pulse width; 0.5% duty cycle)  
POWER COEFFICIENT: < 0.005dB/dB/watt  
TEMPERATURE COEFFICIENT: < 0.0004 dB/dB/°C  
TEMPERATURE RANGE:
