A blocking matrix switch is constructed with switches on both the input ports and the output ports. Each input signal can be switched to only one output port at a time. If your application requires an input to be available to more than one output simultaneously, then a non-blocking matrix becomes necessary. Example block diagrams for blocking matrix switches are shown below the model selection table.
The two most notable advantages of a blocking matrix switch are insertion loss and isolation. Because the matrix construction uses only switches, the insertion loss will be lower than any other matrix configuration. Using only switches also makes it possible to maintain very high isolation from input to output because switches have better isolation characteristics than power divider/combiners. The one disadvantage is that each input is only available to a single output.
Below is a sortable table containing our online blocking matrix switch models. If you can’t find a model that meets your requirements, please contact us. One of our engineers will work with you to pick out an existing model or design a custom model for your application. JFW does not charge NRE’s and our pricing for custom models is in-line with our catalog models.
