Wide-band SSB subharmonically pumped mixer MMIC

To achieve low conversion-loss and high image-rejection performance in the wide band for up and down conversion, an SSB subharmonically pumped mixer using an inphase RF divider/combiner is proposed. The SSB mixer monolithic microwave integrated circuit (MMIC) is integrated in a small area of 1.8 x 1.3 [mm.sup.2] and shows good performance at 21.6 to 30.8 GHz.
