Abstract
In certain embodiments, an apparatus includes a switch matrix and frequency band isolation circuitry. The switch matrix is configured to receive, at an input port, an electrical signal, which corresponds to a transmission signal received at antennas of an antenna array. The transmission signal corresponds to a transmission spatial sector of the array. The electrical signal includes first and second signal portions in first and second frequency bands, respectively, the electrical signal having been generated from an optical signal that corresponds to the transmission signal. The switch matrix is configured to direct, via an output port and in accordance with a control signal, the electrical signal to a first of multiple signal conversion paths.
