Fully-Packaged 71-76 GHz Coherent Photonic Mixer featuring WR-12 Output for CRoF Backhauling

Here, we report on a novel fully-integrated 70 GHz band (71-76 GHz) rectangular-waveguide-type coherent photonic mixer (WR12-CPX) module for coherent radio-over-fiber (CRoF) backhaul links, featuring a high-speed balanced photodetector and a rectangular waveguide output (WR-12) for direct fiber-to-the-antenna connectivity.
