Switching Module SMR1030


Product Description

The switching module is used for switching of HF signals in the frequency range DC … 1000 MHz.


The switching unit is housed in a milled aluminium enclosure with very good RF shielding. It consists of the following sub-assemblies:

–    relay switches SP12T
–    relay driver circuits


The unit is controlled via parallel TTL signals.
