We report the fabrication of a sub-harmonic Mixer at 270-320 GHz, featuring discrete anti-parallel low barrier Schottky diode. The mixer presents a typical Noise Figure of 16 dB in the middle of the band and lower than 18dB all over the band. The reduction in local oscillator (LO) input power requirements is as low as 170 µW for optimal operation conditions. The mixer noise performance remains low when additional LO input power of 500 µW is applied. Both the mixer and the diodes have been fully designed and fabricated at ACST GmbH.
