Wireless Communication Using Fermi-Level-Managed Barrier Diode Receiver with J-Band Waveguide-Input Port

Fermi-level managed barrier diodes (FMBDs) are packaged with WR-3 rectangular metallic waveguides to ensure J-band (220–325 GHz) operation. A broadband amplifier is integrated in the packaged module to be used as a receiver for high-speed communications applications. Wireless transmission experiments at around 300 GHz with data rates up to 32 Gbit/s have been conducted for both direct and coherent detection schemes by using photonically generated RF and LO signals.
