4 Channel Non-reflective SPST Switch

RSWU-4SPDTS is a reliable semiconductor switch with four channels (non-reflecting) for fast, wear-free switching. The module includes four SPDT switches. It is suitable for the frequency range DC … 18 GHz. RSWU-4SPDTS can easily be combined with other components in 50 Ohm technology. The internal switches are non-reflective types which means they provide a 50 Ohm match even if they are not active.



Synchronous Switching

The switching modules inside the system rack SR6-11C can be controlled via an internal binary interface. This way, shortest response times are enabled. Like many other products of Becker Nachrichtentechnik GmbH, this module can be triggered with a rack-internal TRIGGER IO port. This interface provides a precise trigger pulse which complies with the physical execution of the applied switching command. On the other hand, external pulses can be applied to this port in order to trigger the execution of queued switching commands. Therefore it is possible to link multiple racks and devices to a synchronous switching compound.

Optional Controller Unit

The optional controller unit SR6-CU allows advanced and more comfortable control of the switches. This module can be added to the system platform SR6-11C in order to enable location-independent service. The controller features LAN and USB interface for monitoring and evaluating the modules´ temperatures, operating points of the amplifiers and the identification of the modules. Via SR6-CU, the switching modules of the RSWU series can be controlled remotely using SCPI-oriented ASCII commands.

Switching Matrices

Becker Nachrichtentechnik GmbH offers all components for realizing switching matrices. For this purpose, the wide range of components of the WSDU series, the RSWU series and the signal combiner unit WSCU8X1R can be combined. The scalable module system makes it possible to fulfil individual customer needs.

Compact Design

The cost-effective module design is suited for distribution systems of large scale. Up to eleven modules can be placed in the system rack SR6-11C. As the rack features an internal power supply, there is no need for additional cabling. The modular concept allows quick repairs in case of service. This reduces the time the system operation is interrupted and minimizes the MTTR (Meantime to repair).


Using RSWU-4SPDTS, systems like switching matrices can be realized in an easy and flexible way. In applications where multiple signal sources have to be switched to different signal paths, switching matrices are required. Such matrices are used in receiving stations, in production tests, quality assurance tests or in research and development (R&D).
