It is fabricated on a 4-mil substrate using 0.15 μm GaAs PHEMT MMIC process. The on-wafer measurement results show that the conversion loss is about 10 to 14 dB across the W band, as a 10 dBm 48 GHz LO signal is pumped. To our knowledge, this is the state-of-the-art result on low-conversion-loss wideband MMIC SHP diode mixer. The packaged module measurement shows a similar result. Both the simulation and measurement results are shown in good agreement.Millimeter-wave mixer; MMIC[SDGs]SDG7Computer aided network analysis; Diodes; Electric frequency control; Electric losses; Harmonic analysis; High electron mobility transistors; Millimeter wave devices; Monolithic microwave integrated circuits; Semiconducting gallium arsenide; Conversion loss; Millimeter wave mixer; Monolithic diode mixer; On wafer measurement; Subharmonically pumped diode mixer; Mixer circuitsother10.1109/LMWC.2002.10099972-s2.0-0036613087
