<p>The formatter (10) has photodiodes (Pd1-Pd-n) delivering a set of radiofrequency signals (RF1-RFn) obtained from subarrays, and another set of radiofrequency signals (RF'1-RF'm) carried by optical signals (O1-On), respectively, where the formatter delivers the latter set of radiofrequency signals on receiving channels. A reconfigurable optical signal routing unit directs one of the radiofrequency signals in the former set towards one of the photodiodes. Radiofrequency adders (19-1-19m) deliver the latter set of radiofrequency signals equal to sum of the former set of radiofrequency signals. The reconfigurable optical signal routing unit is constituted of an optical switching matrix (17), a wavelength demultiplexer, an optical coupler and a planar selective array.</p> |
