HFET millimeterwave resistive mixer

Paper i proceeding, 1992

A millimeterwave resistive mixer based on a heterostructure field effect transistor (HFET) is described. A minimum conversion loss of 8 dB, including losses in the connectors, filters, substrates etc, is obtained in the frequency range 40-45 GHz. This is the highest frequency of operation reported for this type of mixer.
