Classification: CPC H | IPC H

Claim 0:
1. A communication apparatus, comprising:
a switch matrix comprising a plurality of input ports and a plurality of output ports, the switch matrix configured to:
receive, at a first input port of the plurality of input ports, a first electrical signal, the first electrical signal corresponding to a received signal at antennas of an antenna array, the received signal corresponding to a first transmission spatial sector of the antenna array, the first electrical signal having been generated from a first optical signal converted from the received signal; and
direct, via a first output port of the plurality of output ports and in accordance with a first control signal, the first electrical signal to a first signal conversion path of a plurality of signal conversion paths; and
frequency band isolation circuitry in the first signal conversion path, the frequency band isolation circuitry configured to:
separate the first electrical signal into a first signal portion in a first frequency band and a second signal portion in a second frequency band;
modulate a reference signal with the second signal portion to generate a frequency-shifted second signal portion; and
combine the first signal portion and the frequency-shifted second signal portion to generate a modified first electrical signal that corresponds to the received signal at the antennas of the antenna array.
