Blocking Matrix Switches
A blocking matrix switch is constructed with RF switches on both halves of the matrix.  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.

The two most notable advantages of a blocking matrix switch are insertion loss and isolation.  Because the matrix construction uses only RF switches, the insertion loss will be lower than any other matrix configuration.  Using only RF switches also makes it possible to maintain very high isolation from input to output because RF switches have better isolation characteristics than power divider/combiners.  The one disadvantage is that each input is only available to a single output.  Our RF Matrix Guide steps through the advantages for each matrix switch type.50MS-211    4 x 8 Blocking    DC    6 GHz    1 Watt    Electro-mechanical    Reflective    SMA
