A method of operating an RF system, the method including controlling coupling and uncoupling of RF ports included in an M by N radio frequency (RF) switch matrix including N first-side RF ports and M second-side RF ports, wherein each of the first-side RF ports may be selectively coupled to at least one of two or more of the second-side RF ports, such that RF signals are carried between selectively coupled ports; identifying one or more of the second-side RF ports as active ports, the active ports including a first active port; causing the RF switch matrix to couple the first active port to a first signal port included in the first-side RF ports; obtaining a first indication of reduced performance for a first piece of RF communication equipment coupled to the first active port; and causing, in response to the first indication, the RF switch matrix to couple the first signal port to a first spare port, wherein the first spare port is included in the second-side RF ports and is not included in the active ports.

A non-blocking crossbar switch architecture circumvents the problem present in prior art crossbar switches where input signals may oversubscribe the available inter-die bandwidth. The new non-blocking crossbar switch architecture is split across a plurality of semiconductor dice, including a plurality of interleaved crossbar switch segments. Only one crossbar switch segment is implemented on each semiconductor die. A plurality of input ports and output ports are coupled to the crossbar switch. The crossbar switch is non-blocking, i.e., any one output port not currently receiving data may receive data from any one input port.
