Air Force researchers have developed an innovative optoelectronic device to modulate radio frequency (RF) signals to single sideband (SSB). The device overcomes signal fade and distortion caused by chromatic dispersion common to dual sideband (DSB) modulators. The solution also overcomes previous SSB limitations on output power and adequate spurious-free dynamic range. The result is performance equal to DSB links without chromatic dispersion effects and limited RF fade. A further advantage of the device is lower power consumption than DSB systems.
Potential applications include antenna remoting, radio over fiber, radar, electronic warfare, RF distribution on aircraft and ships, and optoelectronic oscillators
- High Performance: Meets or exceeds DSB link performance while limiting signal fade, avoiding additional distortion, and without suffering from chromatic dispersion
- Innovative: Overcomes previous SSB deficiencies in output power and spurious-free dynamic range
- Low Power: Requires less power than dual sideband solutions
- Patent application 20160080088 is available for license
- Potential for collaboration with Air Force researchers
