Abstract:
Delivering a radio frequency (RF) signal to a remote phased array antenna system involves using an optical modulator at an RF source location to modulate a high power optical carrier signal with a source RF signal S RF  so as to produce a high power transmit modulated optical carrier (TMOC) signal. An optical link communicates the high power TMOC signal to a remote antenna location, where the high power TMOC is split into N optical paths to obtain N reduced power TMOC signals. In each of the N optical paths, photodetection operations are performed upon the reduced power TMOC signal to obtain N reduced power S′ RF  signals which are then constructively combined to obtain a high power S′ RF  signal which is communicated to at least one antenna element.

Claim (Index 10):
A phased array communication system, comprising:\n an optical modulator at an RF source location which is configured to modulate an optical carrier signal with a source RF signal S RF  so as to produce a high power transmit modulated optical carrier (TMOC) signal; an optical link comprised of an optical fiber configured to communicate the high power TMOC signal from the RF source location to an antenna location associated with an RF antenna system, the antenna location remote from the RF source location; a high power optical power splitter disposed at the antenna location and configured to split the high power TMOC into N optical paths to obtain N reduced power TMOC signals, where N is an integer value greater than 1; wherein each of the N optical paths is comprised of\n a photodetector configured to produce a reduced power S\u2032 RF  signal from the reduced power TMOC signal; \n a feed waveguide configured for coupling one of the N reduced power TMOC signals to the photodetector; and \n an optical conversion structure configured to optically convert the reduced power TMOC signal from a less-confined geometry associated with a high power waveguide used in the high power optical power splitter to a more confined geometry associated with the feed waveguide; \n an RF combiner configured to receive the reduced power S\u2032 RF  signal from each of the N optical paths, and constructively combine the N reduced power S\u2032 RF  signals to obtain a high power S\u2032 RF  signal; and at least one phase control element responsive to a control system and configured to dynamically steer an RF beam produced using the high power S\u2032 RF  signal by dynamically controlling a signal phase.
