Abstract: An RF matrix switch has a first set of card slots at selected locations on the chassis and a second set of card slots at different selected locations on the chassis as well as input cards and output cards. The input cards, the output cards, the first set of card slots and the second set of card slots are all configured so that the input cards and the output cards fit into all of these slots. Reroute cards can be provided for any unused card slots. The RF matrix switch also may have an active power management system in which there is a power control switch connected to each amplifier that turns the amplifier off when the amplifier is not being used.
