Bi-Directional 4X4 Switch Matrix

Modern communication standards like cellular, WiFi, ISM and Bluetooth need bidirectional signal transmissions, independent of the multiplex method: TDD (Time Domain Division) or FDD (Frequency Domain Division). BSWM-4X4ER is the right solution to route communication testers to DUTs (Devices under Test) or transceivers to antennas. It offers eight full parallel bidirectional signal paths. Each of the eight output ports can be connected quickly to one input path. Through its extremely wideband frequency range the device is capable of working with latest standards such as Wi-Fi 6E and WiFi 7.

AC or DC Power Supply Options

The BSWM-4X4ER comes in variants designed for either DC or AC mains power supply, catering to both stationary and mobile applications. Both variants support a broad input voltage range, whether AC or DC.

Wear-free Solid State Switches

The BSWM-4X4ER incorporates modern solid-state switching elements, guaranteeing rapid response to operational inputs and an unlimited number of switching cycles with minimal maintenance requirements.

High Channel Isolation

To prevent unintentional signal coupling between different signal types, the device provides high channel isolation. Strong and weak signals in adjacent radio channels do not affect each other.

Versatile Control

The BSWM-4X4ER is equipped with multiple control options for user convenience. It features a local MMI on the front panel, as well as LAN and USB interfaces. Depending on the customer's needs, the system can be managed using the intuitive web-based graphical user interface or through SCPI-based ASCII commands via its interface ports.

Synchronous Operation

The BSWM-4X4ER offers two switching modes:

  • Direct: every switching operation is executed after reception of the command.
  • Synchronous: all switching commands are stored until a "SYNC" command executes the switching operation synchronously.

External Triggering

Similar to several other products from Becker Nachrichtentechnik GmbH, the BSWM-4X4ER includes a TRIGGER IO port. This physical interface enables the device to execute switching operations synchronously across multiple matrices, triggered by hardware signals.
