RF Photonic Links
Pharad offers a comprehensive family of optimized performance RF photonic links for high dynamic range and low loss RF signal over optical fiber transport. The links are packaged as either a transceiver (PXR) module or separate RF photonic transmitter (PTX) and RF photonic receiver (PRX) modules. The links provide electrical-to-optical (E/O) and O/E conversion of wideband RF signals over operating bandwidths covering 3 MHz to 50 GHz. Fiber-optic remoting of a multitude of RF signals can be supported using a single transceiver with a multi-band operating frequency range.
The transport of RF signals over optical fiber offers a number of benefits over conventional RF coaxial cables and waveguide including reduced cabling size and weight; low loss over a wide RF bandwidth; and improved signal isolation. Pharad‘s range of RF photonic links employs proprietary techniques to achieve the best gain, noise figure (NF), and spurious-free dynamic range (SFDR) performance available. They are the ideal solution for supporting the high fidelity bi-directional transport of wideband RF signals over an optical fiber link or network.
Applications include RF signal distribution over optical fiber in communications, radar, electronic warfare, and SIGINT/ISR systems, antenna remoting, aircraft and shipboard RF distribution systems, as well as commercial wireless networks and SATCOM platforms.
