A 300 GHz 45° hybrid coupler for THz wireless communications using subharmonic mixers

A 300 GHz hybrid coupler with 45° phase difference at its output ports for subharmonic mixers in a THz transceiver is presented. It consists of a branch-line coupler with a stub loaded phase shifter fabricated with ±10 microns tolerances. The magnitude and phase imbalances were measured to be less t...

More Information
Summary:A 300 GHz hybrid coupler with 45° phase difference at its output ports for subharmonic mixers in a THz transceiver is presented. It consists of a branch-line coupler with a stub loaded phase shifter fabricated with ±10 microns tolerances. The magnitude and phase imbalances were measured to be less than 0.5dB and 3° respectively from 285 to 325 GHz.
