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.

Broadband - All models are available in a choice of 2
frequency ranges: dc-4 and dc-18 GHz.
TEMPERATURE COEFFICIENT: < 0.0004/dB/dB/°C
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.
Right-Angle Drive - The center conductor of the con-
nector is perpendicular to the control shaft, offering
greater flexibility of applications: panel mounting or
bench setup. All models are bidirectional.

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.
