Abstract:
1. A Multiple Input Multiple Output (MIMO) Radio Frequency (RF) transceiver system comprising: a plurality of RF transceiver Integrated Circuits (ICs) including a first RF transceiver IC and at least one other RF transceiver IC, each of the plurality of RF transceiver ICs including crystal oscillator circuitry; a crystal coupled to the first RF transceiver IC, the crystal and crystal oscillator circuitry of the first RF transceiver IC operable to produce a master oscillation; a master oscillation coupling between the first RF transceiver IC and the at least one other RF transceiver IC, the master oscillation coupling operable to couple the master oscillation from the first RF transceiver IC to each other RF transceiver IC of the at least one other RF transceiver IC; and wherein the crystal oscillator circuitry of the each other RF transceiver IC is operable to produce a corresponding slave oscillation based upon the master oscillation.
