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.

Maximum Active RF Path Examples
2 x 4 Blocking Matrix Switch: 2 active paths maximum
8 x 4 Blocking Matrix Switch: 4 active paths maximum
4 x 8 Blocking Matrix Switch: 4 active paths maximum
8 x 6 Blocking Matrix Switch: 6 active paths maximum
Example Diagram #1
This block diagram shows one possible setting of a 3 X 3 blocking matrix switch. There are three input signals (blue, red, green). Each input signal is connected to one output port. The three colored paths are the three active paths through the matrix. A 3 x 3 blocking matrix has a maximum of 3 active paths.
Example Diagram #2
This block diagram shows a different possible setting of the 3 X 3 blocking matrix switch. Each 1P3T switch can have only one active RF path.
