Manual Step Attenuators
dc to 18.0 GHz
2 Watt
Ruggedized SMA Connector
Description
The Model 9000 series Step Attenuators are broadband
miniature step attenuators that provide excellent perform-
ance 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
o
o
Environmental - Designed to meet most environmen-
tal requirements of MIL-A-24215 (Vibration, Shock,
Relative Humidity to 95% and Altitude).
FREQUENCY RANGE (add Model No. Prefix to
Designate Range):
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 8.0 GHz (AD)
dc to 12.4 GHz (AE)
dc to 18.0 GHz (AF)
Standard Incremental Attenuation Range:
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).
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
o
o
Excellent Repeatability and Long Switch Life.
Custom Configurations Available Upon Request.
MAXIMUM SWR:
Highly Accurate Detent Stepping - Direct drive of
attenuator drums eliminates gears and provides for
excellent repeatability.

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.
