We present the design of a double mirror stub (DMS) based a planar broadband bias tee having an isolation port S31 with 14.45 GHz bandwidth below -10 dB and S33 with 13.1 GHz bandwidth above -2 dB. CST simulation and measured results are in very good agreement. The bias tee will be a part of a new generation of on-chip THz detectors based on zero-bias Schottky diode and high electron mobility field effect transistor (HEMT). Keyphrases: Field Effect Transistor (FET), S-parameters, Schottky Diode (SD), bias tee, broadband THz detectors
