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.

dc - 18

MAXIMUM SWR (Models 115A, 116A, & 118A):

Broadband - All models are available in a choice of 3

frequency ranges: dc-4, dc-12.4, and dc-18 GHz (dc-16

for units with TNC connector).

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.

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)

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.

POWER COEFFICIENT: < 0.005/dB/dB/watt

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

TEMPERATURE RANGE: Operating:

0°C to +54°C

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.

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.

Description

SWITCH LIFE: Over 1,000,000 steps

INDEXING: 36°

The Weinschel Corporation Models 115A through 119A are

a series of broadband, step attenuators in a right-angle

drive configuration, where the center conductor of the con-

nector is perpendicular to the control shaft. They feature

excellent performance characteristics suitable for use in

high reliability 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

attenuators in signal sources, receivers, field strength

meters, spectrum analyzers, etc.
