Variable Attenuators

Models 9003, 9004, 9009, 9010 & 9011 dc to 18.0 GHz

Manual Step Attenuators

2 Watt

Ruggedized SMA Connector

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

Broadband - Available in a choice of frequency ranges:

dc to 4, dc to 8, dc to 12.4 and dc to 18 GHz.

Available Express Models:

AC-9003-69-31

AF-9003-9-12

AF-9003-69-31

Specifications

NOMINAL IMPEDANCE: 50 Ω

Other models may be available for Express delivery.

FREQUENCY RANGE (add Model No. Prefix to

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.

Designate Range):

All Models:

dc to 4.0 GHz (AC)

dc to 18.0 GHz (AF)

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.

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).

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.

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)

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 COEFFICIENT: < 0.005dB/dB/watt

TEMPERATURE COEFFICIENT: < 0.0004 dB/dB/°C
