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 8):
A method for delivering a radio frequency (RF) signal to a remote phased array antenna system, comprising:\n using an optical modulator at an RF source location 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; using an optical link comprised of an optical fiber 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; at the antenna location, splitting the high power TMOC into N optical paths to obtain N reduced power TMOC signals, where N is an integer value greater than 1; in each of the N optical paths, performing a photodetection operation upon the reduced power TMOC signal to obtain N reduced power S\u2032 RF  signals; constructively combining the N reduced power S\u2032 RF  signals in an RF power combiner to obtain a high power S\u2032 RF  signal; communicating at least a portion of the high power S\u2032 RF  signal to at least one antenna element of said RF antenna system; and further comprising dynamically varying a phase of the high power S\u2032 RF  signal prior to communicating the high power S\u2032 RF  signal to the at least one antenna element; wherein the at least one antenna element is one of a plurality of antenna elements comprising an array, and the method further comprises coordinating the phase variation applied to the high power S\u2032 RF  signal to facilitate a phased array beam forming operation.
