Features

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

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°

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.

SMA

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.
