Non-Blocking 4X4 Switch Matrix

Modern signal routing systems need a fast and free access to different signal sources like antennas or signal generators. In receiving systems the large amount different analog and digital modulated signals like broadcast, cellular, Wi-Fi, ISM and Bluetooth need high linearity for a low distortion transmission. Additional a low noise figure is very important in receiving systems for a transmission with high dynamic. The RSWM-4X4 slot-in module is the right solution for modern radio monitoring and signal routing 
systems that must cover the frequency range up to 4000 MHz. The RSWM-4X4 matrix is foreseen for the integration into the SR6-11C system platform. 

4 Inputs, 4 Outputs


Excellent RF Performance

The low noise in combination with the high linearity properties of the device enables the use in professional applications. The matrix offers best channel decoupling.

Synchronous Switching

RSWM-4X4R offers two switching modes:

•    Direct execution of switch commands.
•    Time synchronous switching with help of SYNC commands or a an external trigger signal.

Time synchronous switching can be done either per software with a SYNC command or alternative with an external trigger pulse. 

External Triggering

Like many other products of Becker Nachrichtentechnik GmbH, the devices of the RSWM series offer a 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. Using this port, it is possible to link multiple devices to a synchronous switching compound. 


The RSWM-4X4R is available in two variants:

20 MHz…4000 MHz for V/UHF applications

For applications in the V/UHF frequency range the matrix is available in a frequency variant 20 MHz … 4000 MHz. This variant have high pass filters in each input to suppress unwanted signals coming from e.g. local radio stations in the LW, MW and short wave range.

100 kHz…4000 MHz for broadcast applications

In applications like testing of infotainment components the variant 100 kHz...4000 MHz offers the full transmission of signals from the VLF range up to the UHF frequency range. All typical broadcast signals like (AM, FM, DAB3, DVB-T, SDARS und GNSS) can be transmitted by the matrix.
