      4/30/02
      Model 115A thru 119A
      dc to 18.0 GHz
      Manual Step Attenuators
      2 Watt
      Choice of Type N, TNC, SMA Connector
      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.
      o 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.
      o 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).
      o 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.
      o Custom Configurations Available Upon Request.
      o 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.
      o 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.
      Description
      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.
