High Power Coaxial Attenuator
The Weinschel 119A is a broadband, step attenuator in a right-angle drive configuration, where the center conductor of the connector is perpendicular to the control shaft. It features 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. It can be used either as input or output attenuators in signal sources, receivers, field strength meters, spectrum analyzers, etc.
