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 Sso 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'signals which are then constructively combined to obtain a high power S′signal which is communicated to at least one antenna element.
