Abstract:
1. Apparatus comprising: a hybrid network having at least one hybrid coupler, a plurality of first input-output IO ports and a plurality of second IO ports; a plurality of first circulators each arranged to direct a signal to one of the first IO ports to be directed through the hybrid network to at least one of the second IO ports; and a plurality of second circulators each arranged to direct a signal to one of the second IO ports to be directed through the hybrid network to at least one of the first IO ports, wherein each circulator of the first and second circulators has a first port connected to the hybrid network, and has a second port and a third port, wherein each circulator is arranged such that a signal received via the second port will be outputted to the hybrid network via the first port, and a signal received from the hybrid network via the first port will be outputted via the third port, wherein the plurality of first circulators are arranged to receive a plurality of first input signals and the plurality of second circulators are arranged to receive a plurality of second input signals, such that the first and second input signals are directed through the hybrid network in opposite directions, and wherein the hybrid network is arranged to receive at least one first input signal via one of the plurality of first IO ports, split the at least one first input signal into a first plurality of reduced-power signals, and output the first plurality of reduced-power signals via the plurality of second IO ports.
