Features
o
Safety Mechanical Stop - A mechanical stop between
maximum and 0 attenuation positions on all models
prevents damage to the mechanical drive as well as
preventing large power changes that could cause dam-
age to sensitive equipment.
Choice of Attenuation Ranges - Five standard atten-
uation ranges are available: 0-9 dB, 0-69 dB, and 0-99
dB in 1 dB steps, and 0-60 dB and 0-90 dB in 10 dB
steps.

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: < 0.005/dB/dB/watt
TEMPERATURE COEFFICIENT: < 0.0004/dB/dB/°C

o
Broadband - All models are available in a choice of 2
frequency ranges: dc-4 and dc-18 GHz.
Right-Angle
Drive
-
The center conductor of the connector is perpendicular
to the control shaft, offering greater flexibility of applica-
tions: panel mounting or bench setup. All models are
bidirectional.
TEMPERATURE RANGE: Operating:
0°C to +54°C
Nonoperating: -54°C to +54°C
INCREMENTAL PHASE SHIFT: ~0.5° per dB x f(GHz)
REPEATABILITY: Better than 0.05 dB across frequency
band for switch life.
SWITCH LIFE: Over 1,000,000 steps
INDEXING: 36°
o
o
Custom Configurations Available Upon Request.
Low Deviation from Nominal Value - These Mini Step
Attenuators have flat frequency response over speci-
fied bands and excellent attenuation accuracy.
Deviation from nominal value is low at all settings.
Excellent Repeatability and Long Life Switch -
Repeatability is better than 0.05 dB to 18.0 GHz for
over 1,000,000 switchings of the drum.

The Aeroflex / Weinschel Models 115A through 119A are a
series of broadband, step attenuators in a right-angle drive
configuration, where the center conductor of the connector
is perpendicular to the control shaft. They feature excellent
performance characteristics suitable for use in high reliabil-
ity 50 ohm systems and applications requiring extra-small
components for the precision control of power in discrete
steps. They can be used either as input or output attenua-
tors in signal sources, receivers, field strength meters,
spectrum analyzers, etc.
