Variable Attenuators
Models 9003, 9004, 9009, 9010 & 9011 dc to 18.0 GHz
Manual Step Attenuators
2 Watt
Ruggedized SMA Connector
Features
o Broadband - Available in a choice of frequency ranges:
dc to 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.
o Environmental - Designed to meet most environmen-
tal requirements of MIL-A-24215 (Vibration, Shock,
Relative Humidity to 95% and Altitude).
o 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.
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).
o Excellent Repeatability and Long Switch Life.
o Custom Configurations Available Upon Request.
o 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.
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.
