Abstract
A split ring coupler comprising a stator ring having at least one split in it such that the stator has at least a first and a second end and a rotor ring having at least one split in it such that the rotor ring has at least a first and a second end, said rotor ring being oriented substantially coaxially with and axially spaced apart from said stator ring. At least one SAW resonator is electrically directly coupled between said first and second ends of the rotor ring in series therewith, neither of said ends of said stator ring being connected to ground.
