Characteristics of a millimeter wave drain mixer

Paper i proceeding, 1992

Different drain mixer configurations, based on Heterostructure Field Effect Transistors (HFET), working at millimeter waves were studied. The mixer has a conversion gain of 6-7 dB at 40 GHz with 5GHz RF-bandwidth. This is the highest reported gain for an HFET-mixer working in this frequency band.
