Calibrated low loss radio frequency switch matrix

A system for switching a plurality of radio frequency signals between a plurality of input pathways and a plurality of output pathways, said system comprising:

• a plurality of input pathways with each being coupled to one of a plurality of arrangements in a first succession of micro-electromechanical switches;
• a plurality of output pathways with each being coupled to one of a plurality of arrangements in a second succession of micro-electromechanical switches;
• and
• a processor coupled to said plurality of first and second successions of micro-electromechanical switches for controlling routing of said plurality of radio frequency signals between said plurality of input pathways and said plurality of output pathways.

A radio frequency crossbar switch for switching radio frequency signals from a plurality of input pathways to a plurality of output pathways in a communications node, said communications node providing communications with a plurality of subscriber units, said radio frequency crossbar switch comprising:

• a plurality of input pathways with each being coupled to one of a plurality of arrangements in a first succession of amplified switching elements through a transmission line;
• a plurality of output pathways with each being coupled to one of a plurality of arrangements in a second succession of amplified switching elements through a transmission line;
• and
• a processor coupled to said plurality of first and second successions of amplified switching elements for controlling routing of radio frequency signals between said plurality of input pathways and said plurality of output pathways.
