Millimeter-wave photonic integrated circuit technologies for high-speed wireless communications applications

This paper describes an IC technology for high-speed wireless-link systems, using photonic techniques, which provides 10 Gb/s at 120 GHz. Optical signals are converted to electrical signals and radiated into freespace using Si-based circuitry. Both the preamp and PA utilize 0.1 /spl mu/m gate InAlAs/InGaAs HEMTs with gains of 6-10 dB and 8.5 dB, respectively.
