    • THz UTC-PD Photomixer Module 8100X Series     


    Our THz photomixer module is designed for photonic generation of terahertz (THz) signals in a wide range of applications, including radio-over-fiber systems, antenna technologies, and 6G wireless communications. It combines low insertion loss, high saturation power, and good responsivity with a broad operating bandwidth.

    The module integrates a uni-travelling-carrier (UTC) photodiode chip with a high-performance RF substrate and waveguide in a compact package. It offers excellent linearity and can operate without active cooling, even at relatively high bias voltages.
