			Optical RF Distribution System (ORFDS) Syntonics is prototyping a shipboard optical radio frequency distribution system (ORFDS) that uses photonic links to mitigate EMI issues, freeing the system designer to place antennas and radios without constraints on connection lengths. Syntonics is developing a series of progressively sophisticated RF-over-fiber architectures focusing on designs that use externally modulated CW lasers with relative intensity noise suppressed by balanced detectors and active phase detector linearization techniques.

Steerable high-gain dish antennas are bulky/heavy and usually need a high-profile radome creating aerodynamic drag. PARCA is a conformal, rapidly reconfigurable, electronically pointed, phased array antenna increasing system effectiveness and flexibility. PARCA technology supports multi-band satcom terminals on aircraft and vehicles from L-band at 1 GHz to Ka-band at 44 GHz. PARCA also provides agile high-gain beams for EW transmitters and enables high gain antennas for radar threat receivers.
