Counter-mixing mode integrated heterodyne transceivers

In conclusion, a new detection scheme using integrated heterodyne transceiver with counter-mixing operation was experimentally investigated. A received power sensitivity of-32 dBm at 100 Mb/s was obtained. A simple theoretical model to optimize the receiver sensitivity was developed. Different full-duplex operation schemes were discussed. The counter-mixing mode heterodyne receivers could be a good candidate for broadband coherent access networks.
