Beamformer configurable for connecting a variable number of antennas and radio circuits
Abstract:
A reconfigurable RF routing module may include M RF inputs and N RF outputs, wherein M is greater than N; a plurality of RF switches arranged to select between incoming RF signals; a plurality of RF combiners arranged to combine RF signals to a single RF signal; and a plurality of RF couplers, each associated with a transfer switch and a specified attenuation, wherein the specified attenuation of each one of the plurality of RF couplers is selected so that the RF inputs of each one of the plurality of the RF combiners are combined in a balanced manner, wherein the switches, the combiners, and the RF couplers are configured to route any of 1 to M of the inputs into each of the N outputs.
