Abstract :
A miniature 40- to 76-GHz monolithic balanced distributed frequency doubler is developed in a commercial 0.13-mum CMOS process. This balanced doubler consists of a reduced-size broadside-coupled Marchand balun and two distributed doublers, and suppresses fundamental signals better than 25 dB. The measured conversion losses are 8-11 dB for the output frequencies from 40 to 76-GHz under 6-dBm input drive, with a low dc power consumption of 12 mW. The chip size is 0.64 times 0.65 mm2. To the best of our knowledge, this doubler achieves the widest bandwidth among all the CMOS doublers reported to date.
