115A – 119A Manual Step Attenuators

115A – 119A Manual Step Attenuators

Series of broadband, step attenuators in a right-angle drive configuration.

The Weinschel Model 115A is a series of broadband, step attenuators in a right-angle drive configuration, where the center conductor of the connectorized 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.

 

3000 Series Manual Step Attenuator

High volume fabrication techniques, including injection molding, stamping, broaching and thick film printing ensure a uniform product.

High Reliability – Repeatability better than 0.1 dB over frequency range and life. Weinschel patented detent mechanism, tested to 1,000,000 operations at +75°C, operates dependably even down to -40°C.

Product Uniformity – High volume fabrication techniques, including injection molding, stamping, broaching and thick film printing ensure a cost effective and uniform product.

Low Frequency Sensitivity – Typically 0.1 to 0.2 dB up to 2.5 GHz. o Shock Resistant – 100% spring contact system withstands mechanical and thermal shock and eliminates the need for epoxy or solder.

Single drum configuration

Knob Included  Knobs for both single and dual drum models are included with every attenuator. Characters are screened on the face of the knob insert which is coated with a clear layer of epoxy for protection.

3000 Series Manual Step Attenuator

Broadband miniature step attenuators providing excellent performance characteristics for high reliability 50 ohm systems.

The Model 9000 series Step Attenuators are broadband miniature step attenuators that provide excellent performance characteristics suitable for use in high reliability 50 ohm systems and applications requiring extra-small components for the precision control of signal levels.

The Model 9000 series can be used either as input or output attenuators in signal sources, receivers, field strength meters, spectrum analyzers, etc. The SMA connector furnished on all models are available in either standard or right-angle configuration. The sex of front and rear connector is optional. A knob(s), marked appropriately, is supplied with each unit.
